Tourbillon Desk Toy

This is a tourbillon desk toy that I designed and 3d printed. It uses the internal spring from a retractable badge reel as the mainspring, and can run for around four and a half minutes. Video (with assembly): https://www.youtube.com/watch?v=dB2DK8xBEGc WARNING: I designed this with tolerances specifically for my own 3d printer and filament. The mechanism is a bit finnicky; if you're looking for something that prints and works out-of-the-box, I would recommend trying other tourbillon models that have been tested and iterated on for different printers. Hopefully this is still useful as a reference though! The fusion360 files are available at: https://github.com/kevinbchen/tourbillon-desk-toy Unfortunately I can't find the exact badge reel I used, but it was similar to: https://www.amazon.com/dp/B0D176S2V7?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1 The one linked above has some differences: - Slightly smaller diameter (may need to glue the RachetGear.stl part) - Winds clockwise instead of counter-clockwise. The parts are designed with a reel that winds counter-clockwise (with the open side face-up). For a reel that winds clockwise, you'll need to mirror the entire base, pallet fork, and escape wheel objects: - FrameMiddle.stl - FrameBase.stl - RachetGear.stl - DriveGear.stl - Pallet.stl - EscapeWheel.stl The files prefixed with "PrintedMainSpring" are for the version that uses a 3d-printed mainspring. This one only runs for around a minute, but doesn't require the badge reel component.
