Mamiya Press G-adapter Template

thingiverse

Update 04/11/2020: The M-mount file has been updated for better fit. The tabs were a tad long/high overall, so I shortened them by 1.5mm. The Universal Press lock sliders have long travel with the lock pins engaging about 2/3 the way up, so there is lots of room for error here. With the old version the lock slides were reaching their max travel. If this version is too tight then shave the underside of the hook section of the tabs as needed. If you have already printed the old one then shave the top of the tabs, and add material to the underside of the hook section. ---------- This is a basic templatized version of the original found here: https://www.thingiverse.com/thing:4249403 It is meant for anyone to style the edges/sides according to their tastes and custom builds. This adapter has been verified for infinity focus using ground glass and my most accurate Press lens. I used Tough PLA for the prototype as it has less shrinkage than other materials, and I suggest you use something sturdier or the tabs may break more easily. Not a fault of the design, it's just a small feature and we are talking about holding heavy camera equipment here. Once you take a look at the design you might want to try to make it out of wood, or mill it if you have the equipment as you will always run the risk of the M-mount tabs snapping off. This adapter is compatible with Pro, Pro S, and Pro SD backs. I do not have the motorized 6x8 to test, or other Graflok backs, but I assume it will fit those as well. A big thanks to the original author for making the files available! For light sealing, use as thin of a felt tape as possible to prevent light leaks while not impacting infinity focus.
