Summary

Vee Groove Pulley with Nut Retainers for fastening.

Instructions

I took 2 other scripts and bodged them together to create the vee pulley I needed. I couldn't find a customizer to make a vee pulley with nut retainers. I am not a programmer and I have not used OpenScad before, I just played around with it until it worked. I has the unique feature of being able to create a pulley with a stepped hole diameter. Just set the hole diameter to one size and the motor shaft diameter to another.
I used these customizers:

Thank you Hari Wiguna, droftarts, and the others who contributed to make this customizer.
