The Locking Logs puzzle

cults3d

This puzzle demands precision as it features two identical pieces that fit together in a cross pattern, requiring the solver to discern between them. To tackle this challenge, you'll need four metal pins with a diameter of 4mm and a length of 35mm, similar to those found on the AliExpress website at https://www.aliexpress.com/item/32868697789.html. Before proceeding with your print job, adjust your slicer settings so that it pauses just as the horizontal cavities are about to be printed. This pause will allow you to insert the two pins in their designated positions. Printing is straightforward using standard settings: PLA material, a layer height of 0.2mm, three shell layers, and 15% infill with no material support required. The Fusion 360 design file for this puzzle is included.
