I initially 3D-printed these TPE concave pads for my MTB but decided to head into another direction. I would like € 35 for them. Shipping with DHL tracked: in EU €10 euros Shipping outside of EU estimate of maximum € 22.
50% infill, 5 perimiters (2mm wall thickness) and 0.1500 layer height.
They feel really great on a flat deck like a trampa board! And can even replace bindings. They can fit multiple decks because the pads are flexible and the TPE can be cut rather easily with a sharp knive or scissors. You can attach them with strong double sided flexible tape or glue them on.
Here are some examples from forum members:
