Well this puzzle was supposed to follow very shortly after I completed my Bump Tetrahedron 2
back in February, as I had started building them both at the same time, but other stuff prevented me from finishing this one sooner.
This 'version 3' (silver) is different from 'version 2' (gold) in that it was truncated on opposite corners and also truncated deeper, making all the faces different on each side & smaller overall by 20mm (edge length).
(Silver - version 3)
Edge Length: 145mm
(Gold - version 2)
Edge Length: 165mm
