https://youtu.be/Pes70LTRpu8 "A 3D Printed Slinky Machine" is an easy to 3D print and assemble mechanism that takes all the work out of using a "Slinky" toy! Ok, the Slinky toy is still fun without this mechanism, but the mechanism does make an interesting desktop gadget with its gears, arms and motor in full view. The mechanism uses magnetics to hold the metal Slinky in position during operation, and with a few extra magnets, a plastic Slinky may be used as well. As usual, I probably forgot a file or two or who knows what else, so if you have any questions, please do not hesitate to ask as I do make plenty of mistakes. Designed using Autodesk Fusion 360, sliced using Ultimaker Cura 4.12.1 Engineering profile, and 3D printed in PLA and TPU on Ultimaker S5s.
