Tokyo Safe

This CAD model was designed by Oskar van Deventer, copyright (c), 11 May 2025

Tokyo Safe was designed as a gift for the occasion of IPP 2025 in Tokyo. When taken apart, one can remove the 1000-yen bill from the safe. The safe has four parts: two mazes and two half-pins with a Japanese flag. The two mazes can rotate. The half-pins can be pulled apart and pushed together. Each of the mazes is a simple 4x4 maze. However, as one cannot see the mazes, and as they are solved simultaneously, the puzzle is confusing to solve, albeit quite doable.
