Almost impossible sliding maze puzzle

thingiverse

A compact sliding puzzle can be printed quickly, taking under two hours to complete. The objective is straightforward: guide the player upwards towards the top. Although it may seem impossible at first glance, a solution exists, as evident from the accompanying image. An engaging twist is to reverse the path of movement, which can be particularly effective if the initial solution remains unknown. This reversal can serve as an added challenge or an alternative approach for those struggling with the standard path. To address potential tightness in the player's movement, consider scaling down the XY coordinates slightly or introducing a horizontal expansion (for instance, -0.1mm). My own print experience revealed that these adjustments were sufficient to achieve suitable tolerances. The design was crafted using Fusion 360.
