Mamiya Press G-adapter Template

Update 04/11/2020: The M-mount file has been updated for better fit. Tabs were too long and high overall, so they were shortened by 1.5mm. Universal Press lock sliders have long travel with the lock pins engaging about 2/3 of the way up, allowing for lots of room for error. The old version's lock slides had reached their max travel. If this version is too tight, shave the underside of the hook section of the tabs as needed. If you've already printed the old one, 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's meant for anyone to style the edges/sides according to their tastes and custom builds. The adapter has been verified for infinity focus using ground glass and my most accurate Press lens. I used Tough PLA for the prototype, which 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 when holding heavy camera equipment. Once you take a look at the design, you might want to try making it out of wood or milling it if you have the equipment, as you'll always run the risk of the M-mount tabs snapping off. This adapter is compatible with Pro, Pro S, and Pro SD backs. I don't 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 a thin felt tape as possible to prevent light leaks while not impacting infinity focus.
