The New 3D Printing Thread

My endgoal in this learning process is to be able to make a complete engine without the use of finding a donor engine. Not exactly sure whether that's possible, but most of the parts seem to be readily available. I could be completely wrong.

Likewise. I have made several engines from scratch using 3D printing without using any donor parts. These can haul long trains on blue track, however the loco bodies are too high and too wide to match normal Plarail rolling stock. So my challenge is how to miniaturize my designs.

My printer is an UP mini 2 ES which was unreliable for a couple of years using the supplied ABS or ordinary PLA. Since discovering the more expensive eSun PLA+ last year I have had much better results and now happily make and give away small trains to my granddaugther and many cousins etc.
