Tricklock puzzle

thingiverse

A simple yet challenging puzzlebox that requires assembly and problem-solving skills to open. Unlike print-in-place puzzles, this design demands hands-on involvement, allowing the assembler to grasp its inner workings. The objective is straightforward: simply pull on the handle to unlock the box. However, be warned that excessive force might compromise the solution, rendering it futile. To succeed, use finesse and strategic thinking instead of brute strength. A key is optional but highly recommended as a tool to facilitate opening the box smoothly. For inspiration, designers can refer to a threaded screw mechanism found on Thingiverse, specifically in this model: https://www.thingiverse.com/thing:1686322
