Train Engine (Print In Place)

I've been frustrated with other printable trains as most of them require assembly for the wheels and I've had my son and nephew both break parts off. This model was designed as a replacement inspired by the ClockSpring/FixumDude print-in-place cars. I built the train from the ground up to not have small, weak parts and to not require assembly. I have watched this train get thrown and not a single part of it has broken so it's fairly durable. Over a year later, I finally got more photos, so now there are more than one view. Looking at expanding the train line with new trains too. Train was printed in Printbed Green.
