About this 3D model
This is a simple bracket for a 28BYJ-48 stepper motor. You can insert a M4 nut in the bottom hole and screw in a M4x25mm bolt to secure everything in it's place. Unfortunately I don't have a 28BYJ-48 laying around so I can only show you a rendered image of how it should look like. However, this design was tested by me earlier since I needed it a while ago.
