Yavuz Demirhan is a Turkish puzzle inventor with nearly 150 published designs featured on Puzzle Will Be Played's website. One of his recent creations, Tetradyma, is unique in that it calls for four identical pieces to form a cube shape and can be easily printed without any support material. While challenging, this design is ideal for introducing novice puzzlers to the world of intricate puzzles. The model, with 0.1 mm offset, is based on 8 mm unit cubes. However, scaling should be approached with caution as it may affect the pieces' fit due to changes in tolerances. For optimal printing results, use PLA and a 0.2 mm layer height, 0.4 mm extrusion width, and 40% infill. Slic3r 0.98 can be employed for slicing purposes, with the More button utilized to print all four copies simultaneously.
