Mini Speedtank

The tank has low torque and high grass should be avoided, but on soilid ground its really fun to drift around :D Feel free to modify or remix the tank, STEP and F3D Files are included. 

Building the tank sould be pretty easy, you can look into the STEP or F3D Files for viewing the complete assembly. The chain is conected using short pices of filament. I recommend PLA because it is stiff and doesn't deform that much. All parts can be printed in PLA, except the ones with “PETG” in their name. 4 perimeters and 30% infill should be used.
