Olympus OM motor drive coupling cover

thingiverse

This is a printable cap for the motor drive (winder) connection at the bottom of Olympus OM-1 and OM-2. (OM-3 and OM-4 use different screw-in cap). These cost $15 or more on eb*y, 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 have once bought an OM-1 which was missing the cap and was very rough to wind-on. After opening it, I found all the gears covered in fine sand. The cover is really crucial in keeping the camera in good shape. Even a piece of electrician's tape will do. The bayonet lugs should print without supports. Print on fine settings, with full cooling.
