CAD software - Autodesk Inventor 2024. Feel free to comment if you need some other CAD format, i could convert it.
This part could use of some thinking beforehand, but i slapped it while being extremely sleepy, so sorry about it. It works, though. You can, and should redesign it for yourself if you really want to. I do not guarantee that it would work flawlessly and wont break.
I printed it from PLA, 7 perimeters, 60% infill, adaptive cubic in Prusa Slic3r, 0.3 height. Holds alright for a moment, would reprint & redesign if it fails, though.
All holes already have some tolerance in mind, so it fits quite nicely with stock parts.
TODO:
1. Redesign so it wouldnt need support material (it is possible)
2. Add chamfers
3. Make it not look like a bone
