Doodatable

thingiverse

This project is driven by my efforts to spray paint my 3D prints - essentially, it's an electronically controlled turntable that can be used for painting, possibly 3D scanning or simply presenting other models. The project was designed using openjscad, and the customization options can be found here: http://www.geminidev.be/3d/openjscad/#examples/doodatable The BOM for this project includes: 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 I'm sure there are plenty 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 slowly. The main models can be sliced at 0.3mm. There are two variants available: the default one with a radius of around 9cm and the small version with a radius of 5cm. Circuit and Arduino code can be found here: https://123d.circuits.io/circuits/1836987-the-doodatable Print Settings: Printer Brand: MakerGear Printer: M2 Rafts: No Supports: No Resolution: 0.3mm Infill: 20% Notes: As noted in the main comment, the optional motor connectors are best printed at 0.25mm and printed slowly.
