A simple motor visualizer. STL files and 3MF for a MMU2S in up to 5 colors, as well as a single color STL are included.
This is designed for use with 3 6mm x 1.5mm magnets. Something like this: https://www.amazon.com/Toys-Fidgeting-Magnet-Nemodium-Magnet-Magnetic-Eyebolt-Neodymium-bar-Magnetic/dp/B08TLPKN64/
To print the single color model, use the JO Visualizer-FullModel.stl.
To print the multi-material model, either use the JO Visualizer-3color.3mf and modify as needed, or use the 5 individual part STL files (UpperRightBody, UpperLeftBody, LowerRightBody, LowerLeftBody and MagHolder).
The FreeCAD 0.19 design file is also included.
