Summary Who doesn't need a Taco Train in their life?! I know I did. I designed this to be printed without any supports to make it as simple as possible. It is also expandable if you want to add 2, 3, 4 or more train cars onto the back you can! I printed this in ABS because it is what I had available, but I wouldn't recommend that as it isn't non-toxic. PLA would be better or even better the FDA approved PLA. Any questions or recommendations are welcome! I have a pic of the final product coming soon!
