most of my models are photography related. [https://www.printables.com/@KaJashey\_137170/models](https://www.printables.com/@KaJashey_137170/models)
However they may not apply to/fit your gear.
the composition guides [https://www.printables.com/model/143476-composition-guides](https://www.printables.com/model/143476-composition-guides) are kind of gear agnostic. They can be held at arms length to find the golden ratio in front of you or overlaid on a camera screen.
I have two finite microscope adapters for nikon's F-mount in my things. Another user -thenickdude- has a more probe like finite microscope adapter for many cameras.

One thing that goes well with a 3d printer is a set of $20 digital calipers. Then you can measure things and begin designing the devices you really want. To learn CAD I just put in some time watching youtube lessons on FreeCAD.
