A fun way to recycle those old and broken crayons you've got stuffed in some bin.

Each train needs a bit less than 1.4 inches of crayon (standard diameter) - not counting what stays in the melting pot or cup.

Prep:
Print both halves (STLs are provided for each, right and left) (flip over the STL that is upside down)
Wrap the two halves together tightly with a rubber band - because of the mirror image on each piece, and the interlocking features, the orientation should be pretty obvious. you can also use a clamp to hold the two halves together, but a rubber band is more convenient, especially if you want to chill briefly in the fridge/freezer.

Method I used for melting the crayons:
2 plastic cups (kid cups from most restaurants)
Fill one cup about 1/4 full with water
Places the broken pieces (smaller pieces melt faster) in the other cup and place on top of the water to float in the other cup.
Place in the microwave and run for 30 seconds (check and repeat until there are
