You know that the 3D Printing revolution is in full effect when while browsing Thingiverse you accidentally find out your dad´s got an account and sharing stuff there.
He got my Thing-O-Matic last year when i got a Replicator. He then started from scratch with absolutely no knowledge about 3d printing or CAD and now he designs his own train stuff.
I´m stoked to say the least! =)
We started building his garden railway some ten years ago. We built everything ourselves invluding locos and wagons. To see more of my dad´s railway check out his website: http://www.utj.se

Trying my best at being one myself.
