I made this 12 numbered roulette game. And of course it is fully working! If you google you will find more than enough fun rules to play with! Print one bucket, one wheel, 6 red blocks, 6 black blocks and one in green (sounds much, but the blocks print in just a few minutes).If you don't have the colors, why don't be creative? Make sure you are cooling the print when printing the diamond on the wheel. Press the colored blocks into the right holes. I have not tested to print on an other scale than it is designed for. I used a small steel ball.
