Want to put 5 x 11 x 4mm ball bearings into your Traxxas Street Sport's rear hubs? You can't. They don't fit.

But you can print these and do just that!

Post-Printing

This prints on its own little raft. Just trim it off with scissors or pliers or something. It gives the support something to bite into.

You may have to file or drill out the holes if your printer prints them all wobbly-like. For some reason, Blender kept messing up the inner axle hole, so it might be a little goofy, but this part works well anyway.

Note: whatever happens, you must make sure that little pass-through hole for the axle (the support between the two bearings) is larger than the inner race of the ball bearing. Otherwise, the bearing will rub on the hub and slow you down.
