I made several mahjong tiles to be keychains for a present. Because I do not a multicolor printer I wanted them to be able to be printed in different colors using filament layer changes.

I made 6 different tiles.

1. Red Dragon Tile
2. Character Tile - 1
3. North Wind Tile
4. South Wind Tile
5. West Wind Tile
6. East Wind Tile

Size: 
22.23x30.16x13.1mm

I the keychains I used for them came from amazon in a pack of 50 for $5.
