Made this GoPro mount / riser for a friends long board, but then also decided to make an adapter to mount a bike light I ordered for riding at night. The riser seperates the board and the truck 5mm (pictured is 7mm, this was overkill for supporting a GoPro, and my truck bolts didn’t skrew all the way on with the original hardware, so I changed it).
