Handle for carrying longboards. The handle is as shallow as possible, but still deep enough to let me fit my fingers around it. Supportless print.
For attaching it, I've used two countersunk M5 screws and self locking nuts. Two holes need to be drilled to the board 140mm apart.
I think I've designed a better, side mounted handle, that can be found here.
