CCubes Filter-holding Adapter

**This 3D-printable vintage lens adapter allows users to place optical filters behind the camera lens. **

It has been designed because large specialty filters are expensive and sometimes don't exist while gel filters are fragile and easy to mount. It supports glass-filters with 1-3mm thickness and a 20-39mm diameter aswell as thin 1.5x1.5 inch filter squares.

Both CAD and 3D-printing files are provided in .step and .3mf format respectively.

Supported lens mounts:
- M42
- Minolta MD
- Konica AR (modified design, not cross-compatible, see build instructions.txt in file)
- more will be added

Supported camera mounts:
- Sony E/FE
- Nikon Z [untested]
- Canon RF [untested]
