Summary

Make your own set (91 pieces) of domino's to cut in with a laser cutter.
which also includes the files for a set of rules (Danish and English), 8 player pieces and a "created by" block to make the number of pieces fit neatly in a box.

Also check out this laser cut box that holds a set of domino including the rule block:

Instructions

Preparing the files:

If you just want to make the premade set that I uploaded then just skip the rest of this step (Mexican train - Flora.ai).
If you want to generate your own set then just complete the following steps:

Find an image that you want for the "dots" on the pieces and prepare it for engraving (see flora.ai)
Open the excel and search and replace the "exactPath" with the path for your image
Export the excel as a Text (tab delimited) file
Open the inDesign file and adjust the size of the page to fit your cutting piece
Relink the data merge file in the inDesign file with the new file you made
Now use the data merge function to generate your domino's
If you want to customise it more than this then make your desired changes in the master page.

The 8 player piece should be visually different, and should therefore be made individually, mine was made by adding a number and rotating the flora image used.

The "created by" even though not needed should be made so that all the piece fits in layers of 8 pieces for example in a box like this: http://www.thingiverse.com/thing:714648

Finally the simplified rules are made in both danish and english and can be found in the Train rules file.

Preparing to cut:

Choose the material that you want to use.
Cover it in masking tape to prevent the gas created when cutting to color the pieces.
Create:

Cut the pieces with the appropriate amount of Pew Pew
