GrblGrus's Cube Puzzle cnc/laser

This plan was a generous contribution from GrblGru, the visionary behind the 3D-simulation software for CNC machines known as GrblGru. Despite its seemingly low level of complexity, the puzzle actually requires considerable effort to solve when all the pieces are taken into account. My own build was executed on a desktop CNC machine courtesy of Stepcraft, utilizing 6.5 mm beech plywood with a spiral-toothed 1.2 mm flute. In contrast, the other version was constructed from two layers of Baltic birch plywood, effectively doubling its size. Notably, however, the drawing was specifically designed for use with 8 mm material. For more innovative designs, visit https://www.zenziwerken.de/en/. How I Designed This I created two distinct versions of the DXF file: one tailored for laser cutting, which employs closely nested cuts and minimizes the number of cuts required; the other version is optimized for CNC machines. To utilize this design effectively, it's essential to scale the drawing accurately to match the material width.
