So there's this hot new game where you stack numbers, but I immediately lost two of the 1's. Rather than just make the 1, I made the rest in case someone loses another number. These are the same size, including thickness, as the originals, so they can be used together. These have dimples and bumps that make them interlock when stacked, too.
If you know what game I refer to, buy it. It's cheap, the designers deserve your money, and it's a lot of fun. Trust me, printing these out in 9 separate colors will be a HUGE waste of your time and money compared to just buying an official set.
Prints fine without supports, but there is a lot of short bridging involved.
