About this 3D model

Uploaded is a gear plate and two gears. I've used a 28BYJ-48 stepper motor with this design. The stepper uses a 3mm shaft so that is what is designed into the 24 tooth gear. I've made this for Ardiuno practice. Use short 3m bolts. You can always snap small bolts with the bolt cutters on wire cutters. 2 gears: 12 tooth and 24 tooth. This is version 10. 12 tooth spins without wobble, and 24 tooth fits tight on motor shaft. Printed on an Ender3
