This is a simple multi-piece model I'm sharing for free just because... I use the body as a storage tube because it comes apart. To do this, you must make sure to print the body with 0% infil, no base and a generous brim! Or just use my gcodes generated in cura15.01 It's also tail heavy, so some extra weight is needed in to hold the nose down. I started with this simple model and developed it into a 112 piece cutaway model. For best results, unzip either the obj's, stl's or gcodes, and print each part individually. Wheels and antennae can be printed in groups. If you would like a more detailed version of this, then look for the 112 piece 1/7.5 scale version. Hope you enjoy!
