Timing Pulley Stepper Motor Adapter

thingiverse

I bought a timing pulley that matched my requirements, boasting an 8mm inner diameter hole, but unfortunately, my desired stepper motor only had a 5mm shaft. The provided screws with the pulley were insufficient to lock the pulley onto the stepper motor axle and center it properly. To resolve this issue, I created an adapter that friction-fit onto the stepper motor axle, slightly undersized to fit snugly within the pulley. When secured with the screws, this setup became even more stable.
