cults3d

This puzzle has two identical pieces that fit together in a cross pattern, and the goal is to distinguish between them. To succeed, you'll need four metal rods with a diameter of 4mm and a length of 35mm - exactly like these: https://www.aliexpress.com/item/32868697789.html When printing, make sure your slicer pauses right at the top of each horizontal cavity so you can insert the two pins before continuing. The print settings are straightforward: PLA material, 0.2mm layer thickness, three shell layers, and 15% infill density - no support material needed. After printing, clean out the through holes by drilling them with a 3/16 drill bit to ensure the pins move smoothly through them. The Fusion 360 design file is included for your use.
