After trying to attach a hoverboard to a frame using straps, I realized that all the slick curved surfaces were working against me, so I sought out a way to add several hard mounting points.

I ended up developing a system were I could attach four 1/4-20 threaded inserts to the die-cast hoverboard frame to provide a rock solid attachment for a wide range of applications.

I created four aluminum disks that each have a 1/4"-20 rivet nut attached, and these are bolted to the Hoverboard frame, using existing threaded holes.  I also created a spacer plate with matching holes that can be used a drilling template, and to spread the load to the chassis.
