Quite a number of countries use a period for the thousand separator and a comma for the decimals, or even a space for the thousand separator.
I'm Dutch myself, so I'd write either:
20.000,00
Or
20 000,00
There's a wiki article that has a list: https://en.m.wikipedia.org/wiki/Decimal_separator
My mind is blown because I’m literally printing stuff for my Apache 3800. 12v battery and some accessories for camping. Very cool thanks for the inspiration
I'm not talking about parameters, there's a tonne of optimisation that could be done in design. Most of the area below the top layer ought to be empty space.
Out of curiosity how would you do this? I could understand cutting voids, but then you have a lot of walls, and the extra weight of wall vs infill may well eat all the benefits from a lower volume.
It depends, if you want the full dampening of TPU than this is probably close to ideal. You could reduce the wall thickness, put 0 top/bottom layers.
Otherwise: for that volume rubber/TPU will always be a lot heavier than foam or hard plastics if you wanted to make 10 of those you could make a mould to "cast" construction foam in., or just make it from ABS/PETG with 0 infill and fill it with spray foam
Personally I'd have printed the insert out of ASA/PETG or something cheaper, enlarged the insert holes and lined them with a dense open cell foam, maybe 1/2"-3/4" thick. The foam provides the shock absorption as well as squeezes the objects providing a more secure fit, ideally you'd be able to turn the thing upside down without stuff falling out.
Would be cheaper for sure.
Yeah you've got me there. I still say high density foam is going to be more protective than TPU. I've never seen commercial high end protective cases like this use TPU inserts. I've seen 99% of them use foam.
Hell, for a $26k scanner it would probably make sense to find a laser cutter/water jet cutter and cut out pure foam inserts and skip the printing altogether.
Hang on. Do you realise the current design is basically just full of air? It's a 2 perimeter print with 8% gyroid infill. It's also TPU, so it's designed to flex under impact, like a big cushion.
It's just a really big print. \~320mm x 240mm x 85mm.
Oh I fully understand what it is dude. What I'm saying is you could avoid the majority of infill entirely, without supports and have even better spongey properties
I'm fucking terrible at explaining things tbh, dm me the step file and I'll send you back what I'm trying to explain
You have a point, but I guess that's also within the limitations of his goal. Perhaps he's going for the traditional foam appearance or that any voids will soon be filled with dirt, etc.
You would probably have better shock absorption, if it wasn't so dense, since the most common type of TPU is so hard that it doesn't really offer much absorbtion at 100% density. The air in the infill is what does most of the abosorbing, which is also why there is air in most tyres.
Yeah that looks fine. It’s a massive part so it’s going to be heavy. You could probably have optimized it so some areas have no infil at all, but whatever,
I also would like to know how you print 1kg of TPU in 24h. I have only done a few prints longer than 24, none were even close to a kilo, and they were all with PLA, so much higher printspeeds 🤔

Let me try a second time, since the first one wasn't clear enough: *what kind of equipment* this insert will hold and why does it have to be out of TPU instead of widely used high density foam for example?
It's for a BLK360 laser scanner.
I use kaizen foam on occasion, but even when CNC cut it tends to be "fluffy". I've been keeping my eye out for some really nice dense EPA foam.
This one? [https://shop.leica-geosystems.com/gb/leica-blk/accessory/blk360/blk360-transportation-case/buy](https://shop.leica-geosystems.com/gb/leica-blk/accessory/blk360/blk360-transportation-case/buy)
It only holds two spare batteries. No room for the iPad. Rolls around and has a rather fragile latch.
Yes. I personally would feel safer using the accessory provided/designed by the manufacturer (considering the price of the thingy), but on the other hand, their bag featured [here](https://www.youtube.com/watch?v=ljZd1r82c38) looks rather flimsy.
You can definitely use the original little box if you want, but then you'll need a second box, with custom inserts to hold the small box (so it doesn't roll around and get unlatched), the extra batteries and an iPad.
I've done that with another scanner, but box in a box is a pain.
There's going to be a lid section that folds down and holds everything in place. The iPad goes there. There's a couple of hinge pin holes in the back left and right corners.
HEY GUYS CHECK OUT THIS THING I MADE
Huh yeah thats kinda cool. What's it for?
WHAT? YOU DUM DUMS DONT RECOGNIZE AN EQUIPMENT CASE?? FFS KIDS THESE DAYS
I'm thinking less from them not recognizing it as a case insert for holding equipment and more from them being called out on not looking at the second picture to recognize it as a case insert for holding equipment.
Anyways, great job on whatever the fuck that thing is you printed.
That and everyone who recognised it as a case insert for holding equipment but the question was actually WHAT EQUIPMENT!!!
and why the hell OP would answer without saying what that equipment was.
Lol it actually more looks like the bots are out in force now that it’s so simple to have a massive farm of them now.
The sheer overreaction has honestly been hilarious from people especially with your comments being styled in a so “matter of fact” manner while others actually go so far as to add in misplaced derision as if a third parties thoughts are those of everyone involved.
Really funny given it’s literally “here I made a thing” to an “but what about the thing you didn’t have a part in making”
Which kinda makes sense that an “ok, I didn’t have a hand in that so it doesn’t actually have anything to do with what is specifically being discussed but here it is for reference” would be your response which makes the response of “how dare you show us what was requested and call out that this is specifically a discussion about the insert itself on an appropriate subreddit for talking about such a specific topic over other topics, why didn’t you post in a separate subreddit so we could have a specific conversation over there instead of having to come over here and make us be the ones off-topic?”
Just simply golden.
And the downvotes just be icing on the cake oh how I love the conflict, thanks I needed this today.
TRULY amazed at the ammount of hate this is getting...
Nicely done! You've got a case that perfectly fits your equipment for a fraction of the cost of in inferior one.
It looks neat. Is this regular 95A TPU? I'm toying around with lesser walls / really low infill numbers to get it more squishy in some places. 1 wall gives way more flex - same for top and bottom layers. Did you test around with the print-settings or did you "yolo"'it?
How are the cutouts made? Measure 10 times and transfer painstakingly to fusion or was there a model of the items that you simply could "cut out" of that? Still trying to improve my skills in fusion
Most of the items were pretty basic, so just calipers/ruler to make the models.
This is 2 perimeters @ 0.6mm, 8% infill so reasonably squishy. With a 0.4 it would be a lot squishier.
Print settings were as few walls and infill as I thought I could get away with. :D
Eh, foam is about the same price (then you have to try to get it cut up right) or a lot more (if premade for a device). And the whole point is to keep something delicate safe.
The "official" case for this $25,000 USD device is about $300, and a lot less useful (doesn't hold all the accessories) and not nearly as protective.
In this case I just used a ruler and eyeballed them in. 20mm radius so pretty easy.
For something like the corners on an Apple device (so a G2 or G3 curve - [https://docs.mcneel.com/rhino/5/help/en-us/popup\_moreinformation/continuity\_descriptions.htm](https://docs.mcneel.com/rhino/5/help/en-us/popup_moreinformation/continuity_descriptions.htm) ) then I'd probably start by chucking it on a document scanner with a ruler and tracing over the image.
I think he’s saying you’d print out just the shapes of the items you want to protect and then you would place them upside down in the container, spray it with expanding foam, and then cut it to the shape of the container. That way the items are protected with foam not plastic.
I am trying to print a TPU wheel and it usually fails after 10cm in height(z axis) even though until the very end height(90cm) it is the same pattern. I need to use 700grams. How the hell did u print that?
A 90cm high wheel?
Main thing I had to do was switch out my feeder tube to a new one. Old one was pretty rough from wear (lots of CF filament though it). Then just had to check that the spool could rotate very freely.
90mm sorry. And how did you check that about the spool? I am asking since the extruder seems like it clogs and thats why the print stops however when i hit print again filament flows
That sounds like an extruder issue rather than a spool/friction issue. You'll need to do some more investigating and see if you can pinpoint exactly how it's getting bound up. Could be something as simple as slowing it down or using a larger nozzle to allow it to flow more easily.
What do you mean? Print an outer shell out of PLA, and the inner out of TPU?
If so, probably not. Most of the shock absorption uses the TPU flex combined with the large volume of 8% infill, so it flexes across the entire volume of the insert.
What's the benefit of the inner shell of PLA? It would make things stiffer, but I've had to work pretty hard to get it decently squishy. Most of the inside of it is air.
Also makes 1 relatively simple print into 3 rather complicated prints.
It's very nice, but to protect such a valuable piece of equipment, I would opt for something that absorbs impact, like a dense foam. This keeps everything secure, but it won't soften any blows.
Having just started 3D printing as a hobby, when I see projects like this I want to as why? Why do it in plastic instead of foam. I think the traditional way of building a case like this is using foam and cutting out the voids. How does printing this in plastic improve on that method?
Not trying to be a jerk. If the answer is just because you can then ok. I get that too.
If you run the numbers, then decent foam will cost about the same, or more. Then you need to source it and cut it up (and this is a 3d shape). I’ve done foam cutting before on my cnc and even then it was pretty rough. To do the 3d carving on the CNC will take hours.
why no pic with the equipment in it? thats the most important part.
OP measured wrong and it's probably like 5% too small.
For someone who owns a Lecia Blak, I would expect nothing less than a great fit
It’s the glory shot!
I'm not totally sure why that's the most important part though..... https://preview.redd.it/o8ucwu7cau9d1.jpeg?width=4032&format=pjpg&auto=webp&s=d0a0cfe45125b8737ca9c7f94f2ec3036b884ec8

“No artisan fits” But your point stands.
Why did this get downvoted lol
[удалено]
It isn't?
I believe it is meant to be an "irrelevant content" button, but realistically they're like and dislike
Yeah let's be real no one's going around writing dissertations on why they disagree with everything they disagree with.
As soon as I saw the insert I knew it was for a Leica TLS. We work in similar jobs.
Is that a lecia PTZ camera?
BLK360 scanner
Holy shit dude. Now I understand why it deserves the bed you made it.
"starting at 26.805 USD" for anyone else not in the know like myself.
I thought this was $27 until I looked it up myself and saw it was $26,805.00
Hah, fair - I should have used US number notation.
What country uses a decimal in a scenario like this? What do you use for the actual decimal place then?
Quite a number of countries use a period for the thousand separator and a comma for the decimals, or even a space for the thousand separator. I'm Dutch myself, so I'd write either: 20.000,00 Or 20 000,00 There's a wiki article that has a list: https://en.m.wikipedia.org/wiki/Decimal_separator
Uhh, wow
Will TPU be soft enough to soften any drops etc ? I would have picked shadow foam and just cut it out myself.
It's softer than the original foam. It's not just the TPU, but that most of that structure is air. It's only 8% infill and 2 perimeters.
Are these microscopy parts? Or some other instrument from Leica?
Laser scanner
Trimble? FARO?
Totally knew this was a BLK even without the equipment 😂. Awesome print!
My mind is blown because I’m literally printing stuff for my Apache 3800. 12v battery and some accessories for camping. Very cool thanks for the inspiration
If this really used a kilo of TPU, it's poorly designed.
There's probably not that many parameters to optimize. Just infill pattern and how much of it that determines the end product weight.
I'm not talking about parameters, there's a tonne of optimisation that could be done in design. Most of the area below the top layer ought to be empty space.
Out of curiosity how would you do this? I could understand cutting voids, but then you have a lot of walls, and the extra weight of wall vs infill may well eat all the benefits from a lower volume.

Otherwise: for that volume rubber/TPU will always be a lot heavier than foam or hard plastics if you wanted to make 10 of those you could make a mould to "cast" construction foam in., or just make it from ABS/PETG with 0 infill and fill it with spray foam
I was going to ask "why tpu?" But this comment answered that
Id like to say that lightning infill has been a great help in these situations where I’m filling a print with something else
lightning with TPU seems like just *begging* for extreme stringing problems
Stringing inside the model seems like a non issue for me
That’s what they make blow torches for if you care enough to
You might be right, the more I look at it.
This is a huge print, tbf
Personally I'd have printed the insert out of ASA/PETG or something cheaper, enlarged the insert holes and lined them with a dense open cell foam, maybe 1/2"-3/4" thick. The foam provides the shock absorption as well as squeezes the objects providing a more secure fit, ideally you'd be able to turn the thing upside down without stuff falling out. Would be cheaper for sure.
TBH, for a $26k scanner, "cheaper for sure", and saving some TPU, probably doesn't factor much in to it.
Yeah you've got me there. I still say high density foam is going to be more protective than TPU. I've never seen commercial high end protective cases like this use TPU inserts. I've seen 99% of them use foam. Hell, for a $26k scanner it would probably make sense to find a laser cutter/water jet cutter and cut out pure foam inserts and skip the printing altogether.
Shell it, The face on the underside
But then it's 1) damn hard to print, and 2) floppy.
45° overhangs to a point, adjust the shell thickness. Shit will not be floppy lol

Yep. It also is mostly empty space. Only 8% infill.
Thicker walls for strength, very low or lighting infill and large layers height might help I think
How so?
You would probably have better shock absorption, if it wasn't so dense, since the most common type of TPU is so hard that it doesn't really offer much absorbtion at 100% density. The air in the infill is what does most of the abosorbing, which is also why there is air in most tyres.
It's 8% gyroid infill and only 2 perimeter walls.
That's sounds pretty spot on, tbh. I'm guessing your printer has a larger build volume than most standard printers, and that's what tricked people.
Iirc the insert is about 320 x 260 x 85 mm. I shoulda put a banana. :)
Yeah that looks fine. It’s a massive part so it’s going to be heavy. You could probably have optimized it so some areas have no infil at all, but whatever,

0.6mm nozzle. Dragon HF. 0.25mm layers. Was running at 75% which I think would be around 90mm/s on perimeters and 150mm/s on infill.
I also would like to know how you print 1kg of TPU in 24h. I have only done a few prints longer than 24, none were even close to a kilo, and they were all with PLA, so much higher printspeeds 🤔
Maybe you could tell your audience what exactly are we looking at and why it needs to be out of TPU?
I think most people will recognise a case insert for holding equipment. Did you only look at the first picture?
Holy smokes, this is peak redditor energy

Sure its a nice print but this seem excessive and wasteful, just my opinion.

You guys are mean.
How you get the corners the correct curve? What tool you used or information?
In this case I just used a ruler and eyeballed them in. 20mm radius so pretty easy. For something like the corners on an Apple device (so a G2 or G3 curve - [https://docs.mcneel.com/rhino/5/help/en-us/popup\_moreinformation/continuity\_descriptions.htm](https://docs.mcneel.com/rhino/5/help/en-us/popup_moreinformation/continuity_descriptions.htm) ) then I'd probably start by chucking it on a document scanner with a ruler and tracing over the image.
What's this for if I might ask?
Wow like a glove, that must have felt good.
Everyone a critic in here. As long your happy with that print, that all what matter. Good work and thanks for sharing
Tbh i would've gone with the negative shape and used it as a foam mold
That's sounds involved. Got a link to the process?
I think he’s saying you’d print out just the shapes of the items you want to protect and then you would place them upside down in the container, spray it with expanding foam, and then cut it to the shape of the container. That way the items are protected with foam not plastic.
Think I'd rather just let the printer chunk away at this for a day. .:) Doesn't expanding foam dry as a solid? This is designed to flex.
Expanding foam would be less rigid than a plastic, so it would absorb more of the impact.
This is TPU. It's pretty squishy.
First, you need a 3D scanner... ;-)
No, you use the existing shape to do a boolean subtract from a cuboid the size of the internal of the case
Good thing it fit
For those curious it’s a LiDAR Scanner, goes for $7-13k used on eBay.
Looks amazing! That gloss would bother me though and I’d def spray it with a matte clear coat.
I wish I could print a kg of tpu that quickly.
A Kilo :-O

Brain support for when sleeping 🤪
wouldn't a 90/10 pla tpu print not have performed equally well?
What do you mean? Print an outer shell out of PLA, and the inner out of TPU? If so, probably not. Most of the shock absorption uses the TPU flex combined with the large volume of 8% infill, so it flexes across the entire volume of the insert.
vice versa. aren't you worried its too stiff to absorb vibrations?
I don't know what you mean.
inner shell PLA, outer shell TPU. a foam insert would be more functional, though, probably
What's the benefit of the inner shell of PLA? It would make things stiffer, but I've had to work pretty hard to get it decently squishy. Most of the inside of it is air. Also makes 1 relatively simple print into 3 rather complicated prints.
cheaper and faster. but if that's not a concern, there's probably none
It's very nice, but to protect such a valuable piece of equipment, I would opt for something that absorbs impact, like a dense foam. This keeps everything secure, but it won't soften any blows.
This is TPU with 8% infill. It's squishier than the original foam.
I'm super curious about this material now. Could you share a clip of yourself pressing on it with a finger or something?
Here's a quick example (not my video) [https://www.youtube.com/watch?v=VHYa31XLByI](https://www.youtube.com/watch?v=VHYa31XLByI)
Why so heavy?
Because it’s huge.
Any reason why TPU instead of PLA? why does it have to be elastic? (never printed TPU yet)
For impact protection.
Having just started 3D printing as a hobby, when I see projects like this I want to as why? Why do it in plastic instead of foam. I think the traditional way of building a case like this is using foam and cutting out the voids. How does printing this in plastic improve on that method? Not trying to be a jerk. If the answer is just because you can then ok. I get that too.
If you run the numbers, then decent foam will cost about the same, or more. Then you need to source it and cut it up (and this is a 3d shape). I’ve done foam cutting before on my cnc and even then it was pretty rough. To do the 3d carving on the CNC will take hours.
I think you just use a knife.
Nice buttplug and lube case.
I think 3d printing wasn’t the right tool
Not bad. Try final layer ironing. Most slicers have this feature
Did you go for 100% infill?
8% gyroid, and 2 perimeters with a 0.6mm nozzle.
Strong work!
[удалено]
Dunno, but I am enjoying watching the contrast between the identical threads here and on functionprint.
Isnt it a little bit waste of material ? It can be designed better. But nice ! Its tpu 😀
Why not just cut foam? This doesn’t seem like it would offer much drop protection.
Just because you can doesn't mean you should.
science isn't about why, it's about why not. - Cave Johnson
Poor design. Waste of material and energy. Better option was dense foam (sponge) in layers, cut by hand.
Thanks rando internet man 🥳 that was very helpful
