Drop through longboard risers / shock absorbers

Designed these to add some shock absorption to my longboard with TPU risers and reduce the teeth-rattling feeling I had going over cobblestones. These fit standard drop-through trucks and match the hole pattern for mounting. They're 2mm tall which allowed me to fit them without getting longer screws for the truck mounts, use the scale z command if you'd like them thicker/thinner.

These were printed with Ninjaflex Semiflex on Ultimaker 2+ with 100% infill.
