6. Print-in-Place Twisty Puzzle Box

Impressive and novel, the Print-in-Place Twisty Puzzle Box - Mushroom (Sealed) emerges from your 3D printer in a state of readiness for solving—no glue, magnets, assembly, or hardware needed. You can leave a little gift inside the sealed mushroom cap top of this variant and dare your friends to open it by aligning the internal pieces and twisting the numerous concentric rings. Your printer needs to be exact to avoid fused components because of the 0.5 mm clearance on moving parts, however once printed correctly, you'll enjoy smooth action. To minimize the possibility of printing-induced defects, the ingenious internal mechanisms are 3D-printed with precise tolerances and functional overhangs at an angle of less than 45 degrees. With its premium feel and incredibly pleasant operation, this puzzle is both a beautiful addition to any room and a great mental challenge, thanks to its one-piece construction.
