Acrylic Spikey

A stellated truncated dodecahedron. It is also the logo for Mathematica. My first two attempts were cut from 3/32" clear acrylic. The third is 1/8" tinted acrylic.

I calculated the angles for the triangles and connectors using Mathematica. The angles for the connectors were 65.0126630 degrees, 152.13568896 degrees, and 164.70420180 degrees. The triangles are isosceles triangles with a base of 1 inch, and a base to side angle of 111.4999145471926 degrees and a side length of 1.364257079
