I found myself frustrated with a lack of open-source options for camera parts, especially for the Mamiya press system, so I made my own.
These models are built around a fully parametric design. The *.f3d files can be used in Fusion 360 to generate models for any lens system that uses 3 mount tabs.
As a holdover while I write documentation:
- The tabs are labeled from 1 to 3 (users choice of which to start with) counterclockwise while looking at the rear of the lens
- All of the necessary measurements can be made with a pair of calipers
- The complicated measurements are built around measuring “chords”, or lines that intersect a circle. In this case, the chords we want are straight line distances between the outer edges of the tabs to measure the size of the tabs and their locations.
- You may have to play around with sizing to make the pieces fit for different lens systems. The values I used for the Sony E-Mount parts worked well for my Ender 3 Pro
Roadmap:
| Done | Make initial parametric male and female models |
| Done | Make male and female connectors for Sony E-Mount |
| Done | Make connectors for Mamiya press lenses |
| Done | Make adapter for Mamiya press lenses to Sony E-Mount |
| Make connectors for Nikon F-Mount | |
| Make connectors for Olympus OM System | |
| Make parametric rear lens cap model and make models for all systems above | |
| Make parametric body cap model and make models for all systems above | |
| Write detailed documentation for working with these parametric models | |
| Come up with a solution for locking the connectors |
This is very much a work in progress. Any and all help would be greatly appreciated.
I currently have cameras and lenses in the systems listed in the roadmap, but if you have calipers and a couple hours to print test parts, you can have parts for whatever system you need.
