Skateboard, Longboard Riser Pad

For my "90MM dual hub motor drive kit" I looked for a riser pad to reduce shock and vibrating. Other Riser here on thingiverse doesn't fit, so I designed my own riser pad (shock pad) for my DIY electric longboard. 4mm thick, printed with TPU and 40% infill

All parts used for my DIY longboard are in this Google sheet (mostly german) https://docs.google.com/spreadsheets/d/1oY1xsyZfls_QtgYz6s_KhyBk2TsIkPhy3_0pjxMB-pw/edit?usp=sharing
