A Hollow Mechanical Puzzle Based on Reuleaux Tetrahedron
Takaaki Orikasa, Akihiro Matsuura (Tokyo Denki Univ.)
Abstract (in Japanese) (See Japanese page) 
(in English) In this note, we present a mechanical puzzle based on the Reuleaux tetrahedron with a hollow in the center. The mechanism of rotation is designed on the touching surfaces of the peripheral pieces by fully making use of the convexity of the tetrahedron. The puzzle was designed with 3DCAD software and the main pieces were fabricated with a 3D printer. Through actual manipulation, we confirmed the rotational functionality of the puzzle.
