A single-sided die, for all your single-sided die needs. It will always be a one, and never not be a one. Inspired by Vsauce's Denary Die set

Recommended Printing Instructions:

Print with at least a 4mm brim to ensure adhesion. Low-density (10%) supports are recommended, though it may be possible to print without supports.

After printing, use a knife and/or sandpaper to clean any leftover brim on the bottom, making sure it rolls cleanly and lands with the 1 right on top.
