So recently I've noted nice cheater's die and decided to reverse the concept:
Here's a “bad luck” die, or so-called cursed die- perfect way to prank and annoy your friends at board games.
To make things more annoying, regular dice are also included, as well as a cheater's die to swap it when convenient and make the game more annoying for unsuspecting players- just renember which one is which. :D
Due to differences in infill settings, all dice have similar weights, which makes it harder to notice.

P.S.
There's a small prank from my side as well- I put a bad luck die and a regular one on one build plate, so if you don't pay attention after printing it might take you a while to figure out which is which ;)
