Trinity Coin Haptic Fidget

Uses a thrust bearing and 14 embedded round magnets to create a smooth haptic rotation fidget toy. Use only the center magnet if you don't want the “stops” during rotation. Put a pause command in your gcode using your slicer to pause the print right before the layers over the magnets is started. Insert the magnets, and then continue. Note that the center magnet should be opposite polarity of the six that go around it, and to flip the magnets over when inserting them into the other half so that they attract rather than repel.

Bill of Materials:

• 5x3mm round neodymium magnets - x14
• Thrust Needle Roller Bearing 20x35x4 - x1 (should come with two washers)

The provided 3mf file has colors assigned and a pause added at the appropriate layer, to make one just like the photo. Color changes are easy, but be sure not to remove the pause.
