Rupert's Cube

One of my collegues asked me to create model of Rupert's cube. It is possible to cut a hole through a cube such that another cube of equal size can pass through it. The direction of hole is paralel to shape diagonal of the original cube and the moving cube is centered to this. This model is based on a cube sized 80 mm as edges. Thin connections are harded with halfdisks.This desing contains two parts with gap in 0.4 mm between them. (Around 0.2 mm on each sides)
