D20 blank for engraving
True icosahedron, 22 mm across flats, no numerals.
Drag to rotateDescription
A mathematically correct icosahedron: twenty identical equilateral triangles, 22 mm across opposite faces, the familiar dice size.
There are deliberately no numerals. It is a blank for laser engraving, stickers or hand painting; if you want numbers in the mesh it is easier to add them in your own CAD than to guess at someone else\u2019s typeface.
Print it in resin, or FDM at 100% infill - a die with voids inside lands unevenly and stops being fair. On FDM stand it on a vertex with supports at 0.12 mm layers.
