Puzzle in a half-covered box

Designer:Hajime Katsumoto

Model Introduction

The half-covered box puzzle seems simple: just put five unique-shaped pieces into the box. However, the sliding cover blocks half of the box's lid, making it more challenging. The inside of the box is three units wide, and you need to rotate it to complete the assembly, which significantly increases the difficulty.

Introduction to 3D printing modification

I redesigned and 3D-printed this puzzle. During the modification process, I made the following improvements:

• The sliding parts have been redesigned to adapt to the characteristics of 3D printing.
• A top cover has been added to limit the sliding piece.
• Ensure that the design is as round as possible to prevent the printed parts from hurting players.

I hope you all enjoy this re-made puzzle and share it within the community!
