Standard 623ZZ ball bearing flange

thingiverse

I recently ordered some F623ZZ flanged bearings for a Kossel printer build, but was shipped standard 623ZZ bearings by mistake. I elected to use them and designed this simple part to serve as a flange for the bearing. I tapped the inside with M3 thread so they would stay firmly in place. Instructions I use these with an M3 thread tapped inside. This allows you to tighten them up against the printed bracket so they stay firmly in position without flopping around. There is a shoulder that will contact the inner race so that the bearings will always spin freely.
