TSINY "Gear Box Motor"
grabcad
This is a motor/gearbox combination that is widely available (myself from Amazon), inexpensive and with a lot of configuration options (RPM, Voltage, Torque, etc.). The four mounting holes are verified M3-0.5, and as the screw just grabs, there are six revolutions of grip before bottoming out. The brand changed from Uxcell to Greartisan since I modeled the piece. (Who comes up with these?) I did not model the insides of the motor & gearbox. The exterior is modeled by both data sheet and calipers.
