This was created mostly so I could practice with OnShape, but it's a simple skateboard riser pad. Print it out of something hard if you want a hard pad, soft if you want a shock absorber, scale it in thickness only if you want more or less height (easiest to do this straight in your slicer). I weigh 300+ lbs and have two of these printed at 100% infill in PLA on a longboard and they're not cracked yet, but YMMV. stay safe.
