This is a hub for a the window motors in First Robotics Competition/FRC. This is remixed off of Sykoyoyo's Window Motor Hub to allow use of a #8 set screw if you need a stronger attachment to the motor. This was designed for use on an off season project with a minibot. I added the hole for the set screw because the mechanum wheels used on the minibot would pop off of the motor shaft. This was designed with 3d printing in mind but you can use a CNC mill also. Remixed by Mathew M - FRC team 157 Aztechs
Can be printed on any printer. You do not need to use the exact specs here, you could ease up on the resolution quite a bit. For the set screw to seat properly you can use 4-5 shells to ensure it works well.
Thread set screw hole if needed
The set screw hole in this is not threaded simply because most printers would come out with horrible threads, so just take a tap and thread it
