3D model description

This is my version of a slow rotating motor, I designed to drive a baby mobile. It combines a small DC motor with a AAA battery and a printed power switch in a case able to be hang-up.

Additional parts
* 1x N20 Gear DC Motor (6V) - 30 RPM
* 1x AAA micro cell
* Some solid wire
* 2x Screws M2x10mm with nuts


  1. Print all parts
  2. Cut two wires and remove insulation on 1-2cm on one end each
  3. Wind the blank sides of the wires through the two holes on each connector (slider and contact)
  4. Assemble the parts together with the motor in the case like shown in the pictures
  5. Shorten and solder the wires to the motors contact pads
  6. Close the case with the cap and fix it with screws

I didn't calculated the power consumption yet. I know that one AAA cell at 1.5V may be a little bit undersized for a 6V DC motor. I didn't expected it to be a long running device, but about 45min non-stop duty time should be possible.

Keep in mind, that this is an electric device and the battery clip with loose wire is a dirty hack. Use at own risk and never let this run unattended!
