Every thing is designed in 123d design. This MakerTron is made for flight and exporing. It can traverse rugged terrain thanks to its tracks. I printed it with 15% infill standard speed using raft. i've splitted the parts so that it's possible to print all parts without support material. You need glue to assemble it i used loctite superglue if you print it in ABS you can also use acetone.
