Hi iMaterialise fans,
Hollow Pyramid was requested by Jet Xie. Knowing the Hollow Cube, he wondered whether it would be possible to design a hollow tetrahedral pyramid. The new puzzle uses the same square dovetail joint that holds together Hollow Cube. A pseudo-binary random sequency was used in the dovetail design to keeps the tips connected.
