This is my custom weapon pulley system I designed for my 1lb eggbeater. The pulleys are meant to be 3d printed and the weapon is meant to be CNC machined but I have yet to have my parts machined. The first pulley has a hole for a set screw to help attach it to the motor the second pulley has a locking mechanism so it can easily be coupled and decoupled from the weapon. By 3d printing the pulleys it is now possible to machine the weapon and save cost.
