Mamiya Press Universal G Adapter

thingiverse

Some owners of this camera should know that there's a G adapter for using Graflock accessories and also RB67, but it's relatively rare and expensive so I'm trying to design one myself. The problem is, I'm not an engineer or designer; I'm just a photographer who likes to improvise... haha. Using the Thingiverse file as a basis https://www.thingiverse.com/thing:3825622 This is just a start, and perhaps some adjustments will be needed for full operation, but unfortunately, I still don't have a lens to test it. ***Update April 2020*** Version 2 is now up with many small improvements... - Redesigned locking tab (now it should fit a lot better) - Trimmed some edges for a better overall fit with the original body - Slightly thicker latches for a tighter and more secure fit of the RB67 back I suggest printing all parts and testing first with just screws holding, and after you're sure the focus is right, you may glue both parts. 3FD file is available so feel free to change as you may need. ***Update May 2020*** Tested with a 100mm lens at F3.5; the focus is accurate and there are no light leaks.
