Olympus OM motor drive coupling cover

thingiverse

This is a printable cap for the motor drive connection at the bottom of Olympus OM-1 and OM-2 cameras. The OM-3 and OM-4 use different screw-in caps. These cost $15 or more on eBay, but if it's not for the shelf queen camera, this printed one will work just as well as the original. It keeps dust and dirt away from the gears inside the camera. I once bought an OM-1 without a cap, which was very rough to wind on. After opening it, I found all the gears covered in fine sand. The cover is crucial in keeping the camera in good shape. Even a piece of electrician's tape can do. The bayonet lugs should print without supports. Print on fine settings with full cooling.
