Made this corner units as I needed something strong, but relatively quick to print, to hold a bit of equipment on a wall. Would mount anything 48mm high with right angle corners.

I used it to mount some video hardware to a wall backstage.

Uses a single screw (wood in this case) to hold the bracket to the wall and clamps the item being held to the wall.

‘scooped’ the sides out so as to not block ports, switches etc close to the edge of the item being mounted.
