This is a tile set for Julian Anstey's Print and Play game, '30 Rails'.
Silicing was split into processes within simplify3D to have 0.15mm regions on the faces of the tokens, a material change near the center (for color contrast), and the center region printed at 0.31mm layer heights.
Infill can be anything that works, use more or less to achieve desired mass/density, top layer support, etc.
Print the following number of each model:
1x board (THE BOARD MUST BE SCALED SLIGHTLY, I printed at 103% and it worked well)
1x bonus square
7x each type of tile piece (named one, two, three, four, five, six)
I changed the rules slightly so that instead of rolling to determine the track type, I simply draw from the bag. This allows you to include more or less pieces in the bag to adjust the probabilities. You can, of course, also play with the normal rules too.
The tiles have 1.5mm deep embossing for the symbols, so put your color/filament changes at something like 1.45mm from each of the faces of the tile. For the MK3, I use the M600 gcode, your printer may vary.
You could also just print it in one color and paint it.
