A motor mount for JGY-370-CE worm drive 12v motor that you can find on ebay etc fairly cheep. The motor I used had 4 M3 mounting holes other motors have different hole paterns.
I needed M3 x 6mm screws to hold the motor and used screws for mounting computer fans to mount to the mdf base in the picture.
Printed without support with about 15% infill at 0.2mm layer height.
