3030 Extrusion Rubber TPU Foot (Cubic?)

After creating and printing a round foot for my printer, I didn't like the aesthetic of it when combined with the square edges of the 30mm x 30mm aluminium extrusion frame so I made this foot to more closely match the shape of the frame.

I haven't printed it yet but I'm guessing something like a 50% infill should be about right.

Edit. I printed at 40% which was fine. I think anything above this would reduce the dampening effect.
