Rail Cars for the Thomas trackmaster sets. Would probably also work with Brio if you used a different connector.
I started with http://www.thingiverse.com/thing:358779 and
and heavily modified it. I had 3 goals in mind.
- I wanted to be able to "snap" this together as much as possible straight off the printer without using any glue.
- I wanted to avoid supports as much as possible, the only thing you should need it for is the roof of the "box car"
I wanted the set to be modular so you could print one of the Rail carriage bases and then have the different bodies fit onto it. I also designed it this way in the hopes that others would create more cars to fit the carriage. You should be able to take the "flat car" and scale many of the other designs on thingiverse to fit onto it.
Please post your remixes or prints. I would love to see them!
I printed all of these using PLA. The box car body is HatchBox Wood filament.
