Mounting plate with 10 Lego technic compatible peg holes that clips round a standard, cheap 28BYJ-48 unipolar stepper motor. The stepper motor drive axle is perfectly aligned so as to mesh with other technic gears.

Printed on an TronXY P802, 0.2mm layer height in PLA+

After printing, be sure to run through the peg holes with a 4.8mm twist drill or reamer.

The design has two holes that take M4 bolts for extra security, but I found that the snug friction fit was enough to keep the stepper in place.
