Electric Train

This is a model train (1:72 scale approx).I designed in CAD. It is driven by a "hobby" motor (5V) and is powered by two AA batteries. The case, cover, wheels and similar components are meant to be 3D printed while batteries and wiring have to be sourced externally, In theory, the train should work (with minor changes) and I will be making a smaller, simpler version in the near future. Have fun modifying and building it! Comment if you think this design is plausible!
