Mixup puzzles usually live on cube axes. Guan Yang's Mixup Skewb Prism refuses: skewb corner rotations intersect four logical layers running perpendicular to a hexagonal prism's axis, letting centres migrate like edges and bandaging bloom unpredictably.

Produced by LimCube's 3D-printing workshop in 2023, it remains an expert collector's object - mainstream tutorials barely exist, which for a certain kind of puzzler is the entire recommendation. The black edition keeps focus on the geometry's strange beauty.

For solvers whose shelves already groan with solved mysteries.

Features:

• Non-cube-axis mixup mechanism
• Skewb corners crossing perpendicular layers
• 45° turns cause center migration
• Expert-tier printed collector piece
