This is the eight sided die (d8) in my hedron series. This die measures about 18 mm (0.7 inch) across the opposing faces, and about 42 mm (1.6 inch) from tip to tip. It weighs about 18.5 grams. The die is well balanced and gives a fair roll. This design is hollow for better results when printing in steel and the other metal options. The solid version, for printing in plastic, can be found here
