The Thulium is a 6x9 medium format camera made for wide and super-wide angle lenses. Focus is done by scale. It was made mainly as a proof of concept, to test out some features for the next Holmium prototype. I also explored the capabilites for more complex patterning with 3D printing, as it doesn’t alter cost to do so.

Files are available, but there are issues and you will need to experiment.
