Body Cap for Mamiya RB67 Pro-S

thingiverse

Edit 3/16/2021 - V2 cap modified slightly to eliminate minor interference with lens mount when cocking shutter. This is a body cap for the Mamiya RB67 Pro-S. It fits on the front of the camera when the lens is removed preventing dust and debris from entering the mechanism. It is marked with the camera model for identification. Unlike the Mamiya RB67 lenses, this cap is a press-in fit, engaging the inner radius of the lens mount firmly with springy fingers. It is held in place with friction and fits well on my RB67 (YMMV, depending on how you set up your printer). For a cap, this is a much simpler solution than the original RB67 breach lock mechanism. The cap does key into the mount, so rough orientation is important when applying it to the camera body. The tabs on each side of the cap give a good gripping surface for removal. Print graphics side down on the bed. No supports were necessary with my printer.
