This is an icosahedron (or dodecahedron, depending on how you look at it) made from a modified version of Sturdy Edge Module (StEM), a 90-degree unit variant designed independently by myself and many others. There are 30 units used, each from 2:1 paper. I previously folded a similar piece from 60° units.

This model was folded from Cromático paper which is transparent like the better-known Glassine but much thicker (100 gsm). The paper’s folding properties are like those of tracing paper, meaning that any sharp crease is likely to tear. This makes it OK for most modulars but unsuitable for tessellations (which is a pity because the paper looks really nice).
