SpaceWarp-compatible 3D printed rollercoaster last update : 01/12/18 Inspired by the (now out of production) Spacewarp roller coaster system http://www.angelfire.com/journal/scottmills/SpaceWarp/spacewarp.html. This library is based on this thing: https://www.thingiverse.com/thing:63210. Thanks to him for adding the openscad file. I have reworked everything to provide missing items like the ball elevator, another type of support and the switch I used the duplos plate as a baseplate a video of my thing https://youtu.be/lBIr7oJcXWI All parts can be printed easily.
