80mm Outer Diameter focus gear for the Contax Zeiss 28mm f2.8, 55mm f 1.4, and 85mm f2.8.

I've included the G-Code in the additional files based on using an ender 3 to print this. The Gear was made in Blender so if you import into Cura scale it up so that the dimensions are 80mm x 80mm x 13mm.

Some electrical tape can be used on the gear to make for a tighter fit.
