Experience a challenging 6 x 6 x 3 puzzle featuring a ring and four identical blocks. Achieve the final shape by fitting the pieces into the ring and sliding them without rotation. The original design can be found at http://puzzlewillbeplayed.com/663Ring/Intrude2/. Additionally, you can utilize the provided .xmpuzzle file in Burr Tools for solving assistance. To create this puzzle, print one ring and four block copies. The STL files are designed based on 10 mm unit cubes with a 1 mm bevel and a 0.1 mm offset to ensure smooth piece movement. For optimal printing results, use a 0.2 mm layer height, two perimeters, 20% infill, four bottom layers, and six top layers to perfect the surface finish.
