Are you sick of the weird faces on your kid's toy trains? Why not replace them with something cooler (or maybe weirder?)

3D Prints of their own faces!

I tried this out for my nephew's 4th birthday. He LOVES trains, and he lives far away from the rest of the family. So I thought it might be a good idea to bring his cousins to him in Train form.

I used the Thomas Wooden Railroad trains for this, but I'm sure you can just as easily do it with one of the other brands.
