I designed a little robber mask to put on the robber for the Settlers of Catan board game! It has a bit of a snap edge, so it'll be a fit on the tighter side (won't fall off!). Printed with black PLA at 200/60.

If the print doesn't fit (too tight/loose), you can scale it up/down by a bit (~0.5mm) in all directions - thanks to RevHazlett for bringing this up!
