TPU frame

Sandwiched between the carbon fiber panels is the TPU frame. The frame houses and protects most of the electrical components. The planetary gearboxes fit snuggly into holes in the front of the frame. two compartments make up the rear of the frame. The electronics compartment is the smaller of the two and features 4 standoffs for the 4-in-1 ESC to mount on to. The larger compartment is for the 450mAh 3s battery.

The frame is printed with zero top and bottom layers, this is to save weight. Rigidity in the X and Y axis comes mostly from the carbon fiber panels, so the top and bottom layers become redundant in this case.

Six perimeters are utilized to ensure vertical rigidity. Infill is Cubic at 50% density. This part took roughly 5 hours to print.
