Doodatable

This project was motivated by my attempts to spray paint my 3D prints - essentially, it's an electronically controlled turn table which can be used for painting, possibly 3D scanning or just presenting other models.

The project was designed with openjscad and the customisation options can be found here:

The BOM for the project are:

* 1 x roll of Painter's tape
* 1 x Arduino or compatible device
* 1 x 28BYJ-48 Stepper Motor 5V
* 1 x ULN2003 Driver for the motor
* 3 x 16mm Marbles or steel balls
* 2 x Microswitches
* 10 x Connecting wires (male/male)
* 1 x 400 point Breadboard

Though I'm sure there are lots of alternatives to this if you don't mind hacking the Arduino code or doing some soldering.

I've provided some female/female connector parts for the motor - if you want to print these, my suggestion is to slice at 0.25mm layers and print slow.

The main models can be sliced at 0.3mm. There are two var
