A Pyraminx with exposed core.

This is the tetrahedral puzzle which had been missing for years. The cuts are placed differently to expose the four central triangles which together form the immoveable core.
The puzzle was built from a Dino Octa but the result resembles a Pyraminx so strongly that it is used as entry for the mechanism. This reflects also the solving signature: HC1[F3 C4/2 Zz1/2][F3 C4]
Edge length: 200 mm
Weight: 400 grams
