17mm Hex Hub for 6mm shaft motor.

thingiverse

Wanted to cut weight from using brass/steel hubs so designed a beefed up version for 6mm shaft motors on <b>high-speed</b> robotics project. Printed in ABS/ASA at 100% fill to maximize strength. Holes for M3 grub screws and M4 wheel bolt will require tapping or a little force to get screws to tap themselves easily. 6mm Shaft and 17mm hex end should be a tight fit. If too tight maybe under-size by a small margin, or reduce over extrusion to get a good fit.
