Build paper models of various kaleidocycles

Three pdf-files for print out are available containing nets of kaleidocycles. Cut out, fold and glue carefully as indicated on the sheets to obain twistable models. The heavier the paper used, the more stable the models.

Kaleidocycle n=8 regular
consists of 8 regular tetrahedra.

Kaleidocycle n=6 closed
consists of 6 tetrahedra having all faces equivalent and isosceles. In certain positions vertices meet in the center of the kaleidocycle.

Invertible cube and bolts
6 tetrahedra, all faces right-angled. One position allows inserting two "bolts" such that a cube emerges from the geomety.
