Mamiya RZ67/RB67 prism cover

thingiverse

Cover for the Mamiya RZ67 prisms. Worked for me, but use at your own risk :) Uses two M3x8mm screws (something low head... either low profile SHCS or philips) to replace the locking pins on the camera. I threaded them directly on the part, leaving ~1.5mm underneath the heads. This allows the threaded part to protrude slightly thru the back - enough to further fix them with epoxy. *UPDATE 5/19/2020: the original file (square corners, only 2 slots on the back) DID NOT work with RB accessories. I uploaded a new file (rounded corners, 4 slots) that I tested with my RB67 metering prism and seems to work fine.
