A riser to fit between a longboard truck and the board, with an integrated handle. My board doesn't have a kicktail, so i can drag it behind me like a wheeled suitcase instead of holding onto the truck itself.

Print in ABS or hard TPU with a lot of walls, high temp and a good amount of infill 25-50%. It was very snug at 0.0 hole expansion, I suggest making the screw holes slightly larger in the slicer settings, ~0.2mm. Scale the model to your liking on the z-axis. I printed it at 8mm height.
