After three and a half hours of pinning and hot gluing the LED string in place, Squishy Dodecahedron is assembled!
@geekmomprojects Two down, only 3 more platonic solids to do before you have the full (D&D) dice set?
@avatastic I've already done the two hardest ones, so the other three might happen!

@geekmomprojects The only caveat is that the tetrahedron should be easy to misplace, but painful to find with bodily extremities.

We call them roleplay caltrops for a reason, after all.
