This is a little Engine that can run on BRIO style Tracks! Not sure if it is a Diesel or Electric Locomotive - your choice! Also added the 123d Source Files so you can adapt it to your needs! At the moment without couplers - so it is up to you to construct some fancy stuff... I am sure I will make some later, if I have more spare time! 12.06.: Update: Added Hook & Ring Coupler, drill a 5mm hole in the body and use some glue!Made with Makerbot Replicator 2x, Nozzle Temp 235 deg., Printbed 110 deg. 2 shells, standard setting!
