Surface Wall Clamp(s)

Simple clips to hold the surface in place, snug fit without the keyboard attached.

Slots in from on top and rests securely in place, space left for charger / USB port / Stylus.

If you wanted to hold it in place on a more perm basis just print 3 or 4 and screw it in place (would mean no space for the stylus / 3.5 jack).
