WARNING: You need a well-tuned printer to print this! This model requires you be able to print in vase mode with 60 degree overhangs.
All testing was done with a 0.4mm nozzle, however a 0.6mm nozzle should work just as well.
Recommended print settings: 0.65mm line width (yes, you can print with a larger line width than your nozzle!) 0.12mm layer height Cooling fan on max, or set to where you can print 60 degree overhangs.
There are two models available here: One behaves the same as a tile with a Y shape, giving a 50% chance to tip over and go either left or right. The other is the same but has gutter holes that allow the ball to fall through the bottom of the tile.
Note that the Hextraction game board is on a 30 degree slope, so having a 30 degree incline on the pathway makes it level with the surface the board is sitting on.
