Scaled up to an approx 150x150mm footprint. Holes sized for 5/16" bolts. Added cross-brace 1/4" threaded rod.

I intend to add some felt padding around the hook surface area where the tablet rests.

Thanks to Landon Cox (inhale3d) for the very nice original design.

One further change I might make if the occasion arose would be to eliminate the ring of material around the bolt heads on the hooks. It just gets in the way of the wrench when you go to tighten those bolts.
