Mobius Kaleidocycle box (kinetic ring box)

prusaprinters

<p>A neat box with a unique opening mechanism.</p> <p>I reverse engineered this model by watching this reddit post: <a href="https://www.reddit.com/r/mechanical_gifs/comments/e88l83/this_engagement_ring_box/">https://www.reddit.com/r/mechanical_gifs/comments/e88l83/this_engagement_ring_box/</a></p> <p>Go show that OP some love and maybe buy one of his metal boxes. His box is much better than mine. See my box in action here: <a href="https://www.reddit.com/r/mechanical_gifs/comments/e9g73p/i_made_a_3d_printable_version_of_that_kinetic/">https://www.reddit.com/r/mechanical_gifs/comments/e9g73p/i_made_a_3d_printable_version_of_that_kinetic/</a></p> <p>This print requires 18 m2 washers (3 washers at each joint) and 6 m2x10mm socket cap screws. shorter/longer screws may also work. The washers i used are about 0.6mm thick and i picked the flattest ones (concave/convex, or bent washers will mess up your joints and your box won't look as nice). The washers really help the joints sit flush and perpendicular.</p> <p>I designed some magnet pockets for some magnets i had on hand. I don't think the magnets are really necessary, but they do help the box snap closed into the close position. Glue the magnets in place but make sure to install them in the correct orientation so they attract each other when the box is closed. The magnets are 10mm x 5mm x 2mm from eBay: <a href="https://www.ebay.com/itm/20pcs-Strong-Magnets-Block-Square-Rare-Earth-Neodymium-Small-Magnet-10X5X2mm/142721269116">https://www.ebay.com/itm/20pcs-Strong-Magnets-Block-Square-Rare-Earth-Neodymium-Small-Magnet-10X5X2mm/142721269116</a>. If you do use tiny magnets, be sure to keep them away from kids.</p> <p>Edit: updated to version 2 with better magnet orientation.</p> <h3>Print instructions</h3><p>Print 3 FRONTpanel.stl and 3 BACKpanel.stl. Insert the m2 screws through the first panel, then 3 washers, then screw directly into the other panel.</p> <p>I printed mine at 0.24mm layer height, 0.5mm extrusion width on a 0.4mm nozzle. Filament is Atomic Filament's ruby red transparent color. Try to avoid elephant's foot, because it will make your joints sit at funny angles and the final box won't look as nice.</p>
