3030 Extrusion Rubber TPU Foot (Cubic?)

thingiverse

Creating a custom foot for my printer, I wanted to improve its appearance when paired with the square edges of the 30mm x 30mm aluminum extrusion frame. So, I designed this new foot to closely match the shape of the frame. I haven't printed it yet, but I'm guessing that a 50% infill should be sufficient. However, after printing at 40%, which turned out fine, I think anything above this would actually reduce the dampening effect.
