This thing is a scale fuel tank for your Traxxas TRX-4 truck. I've been adding more scale accessories to my truck and designed this tank to add a realistic-looking tank to the rear of the frame.
The tank mounts between the frame rails, simply by removing the rear bumper mount, sliding the tank into the frame rails, and remounting the bumper mount. The tank is captured in the frame without additional hardware and cannot fall out.
Print this part with very low infill to keep the weight down as rear weight can hinder crawling performance.
Be sure to check out some of my other scale RC things for more as I'm adding to the list frequently!
Print with the large flat side facing the bed and you won't need any supports. Printed with low infill and 2 perimeters, but 6 top layers proved to be the best combination for light weight and proper printing.
