Found a few sticky strip mounts online but none held the HSW frame in place, so here is my design with a tapered hole and simple tapered peg that holds the HSW frame back, to remove just push the peg back out.  As for what to use when sticking these to the wall, i've found nano tape the best as it holds VERY well but also peels off cleanly when removing from the wall. (twist the base to remove nano tape when attached to the wall)
