DIY Motorized Turntable

Introduction: DIY Motorized Turntable

Made from reclaimed and 3D printed parts...

Minimal cost

Out of pocket is only a dollar or two worth of filament, a couple of screws and nuts, four adhesive pads.

Step 1: Print the Parts

STL files can be found on Thingiverse...

My parts were printed with a 0.8mm nozzle to minimize printing time.

Though a standard 0.4mm nozzle can be used.

Step 2: Hardware

Reclaimed Hardware / Parts:

  • Turntable gear motor from old microwave - 120v - 5/6 revs/min - 7mm shaft.
  • A/C power cord
  • SPST rocker switch

New Stuff:

  • Two 4mm screws and nuts
  • Four adhesive feet / bumpers. I had some felt pads laying around to use.

Step 3: Tools

3D Printer

Soldering Iron / Solder

Screwdriver(s) / Wrenches / Pliers (depends on the screws you have).

Wire Stripper / Cutter / Knife

Step 4: Motor and Switch

Install motor

  • Use the 4mm screws and nuts to attach to inside of base unit.

Install SPST rocker switch.

Step 5: Wiring

Insert the power wire.

I just knotted it for strain relief.

Be sure to leave plenty to reach the motor.

Strip the outer sheath.

Cut and strip the wires to length.

  • One directly to the motor.
  • The other to one tab on the back of the switch.
  • Then from the other tab on the switch to the motor.

Solder the wires in place

Step 6: Finishing Up

Install the pads to the bottom of the base.

Install the turntable top to the motor shaft.

Plug in the power cord and test.

    Tip 1 year ago on Introduction

    I love your design. I do have to caution anyone considering this project that the current design is unsafe for two reasons:
    1) There is no cover, so it is possible to touch wiring with line voltage. This could be deadly, or at the minimum painful!
    2) There is no fuse. It is possible for the turntable to catch fire. Especially with a used motor, this is a real risk.

    I urge anyone considering this project to add a fuse between the power cord and switch, and to cover the bottom of the turntable base.
