About this model

I needed a focus gear for my Jupiter 9 lens to use with my Zhiyun and Moza gimbals. So, I designed one. Unlike the other gear I made for the Nikon 50mm f/1.4D AF, this one's seamless, prints in one piece and requires no screws or other hardware. It's designed to fit into the ridges of the focus ring on the Jupiter 9 lens and if your printer's tolerances are dialled in right (check "Horizontal Expansion" Cura if it's a little too lose or tight) then it should fit very snugly without shifting - especially if you print in PETG as I did.
