Motorized turntable for spray painting miniatures and other parts. Variable speed. Remote control (wired). In addition to the 3D parts which design are provided here, you will need:
A DC motor with gearbox (DC 12V Reversible High Torque Turbo Worm Gear Box Reduction Electric Motor 5/6/20/40/62RPM(20RPM) by Walfront, less than $20 on Amazon)
A motor controller (DC Motor Speed Controller (PWM) Speed Adjustable Reversible Switch DC Motor Driver by Yosoo, again less than $20 on Amazon)
An on/off switch (see picture) that fits a 17x12mm hole
4x screws M3x6 to secure the motor
4x screws M3x10 for the controller lid
- A 12V DC wall power supply (500mA should be fine)
The motor controller comes with a potentiometre to control the speed, and two momentaneous push buttons for clockwise and counterclockwise rotation. Unfortunately for continuous rotation without you pushing on the button, you need to provide a switch that you will install in such a way to short one of the push button (expose the wires then solder the switch). Installing the circuit inside the controller box should be relatively straightforward, feel free to contact me if you have any question. For the external wiring, make sure you have the correct polarity on the 12VDC input (+/- is clearly identified) and if you are not sure about where to connect 12VDC input and output to motor, see my picture with the lid open, black wire is 12VDC input, beige wire is output to motor. Polarity to motor does not really matter (except if you really want to have a certain color code for rotation direction). A 3 to 4 feet wire is more than enough, it is your guess for your application.
The lid is secured with 4 screws M3x10. When the controller is connected, you should see a red light on the circuit board.
Use 4 screws M3x6 to secure the motor in the box. Connect the wires to the extension cable that goes to the motor output on the controller circuit. Make sure you use something (e.g. shrink tubing) to prevent short. The box does not have a base, I did not feel it was necessary. For more heavy work, you might want to design one (or ask me and I'll design one, but a simple square glued should be ok).
The round plateau should fit nicely on the motor D shaft. I've put a small pin on the flat side, on the exterior rim, so that you know how to insert.
DO NOT FORGET to remove the supports inside the grooves, it will help if, for example, you use putty to stick your miniature to the plateau.
You are good to try it now. It might be a little overkill and it is not really cheap, but so much fun and satisfying to use :-)

20%, gyroid for plateau, as easy to remove as possible for controller box!
