Some cool cnc milling and turning images:
CNC x Continuous Surface

Double sided CNC milled MDF board.
Each floor is the same model but turned upside down on every other level, providing two types of space with one mold. The unit can also be linked at its sides to expand both vertically and horizontally.
The overall form is a continuous surface. The 2.5mm thickness of the walls/floors show how efficient the surface acts in transferring loads (surface active structures) while staying lightweight. (personally i’m very happy with this model because it feels so sturdy yet so light!)
