White board half wall mount

A simple half-wall mount for a whiteboard, with slide rail and lock-in-position for stowing it away when not in use.

Uses slide rail from Accuride, 3832SC which you can get in Sweden at Bauhaus (their webpage sucks, don't even think about searching for slide rails there).
From Accurails webpage: https://www.accuride.com/en-us/products/3832esc-self-closing

Materials used:
Two wooden square rods of 20x20x450 mm with cutouts to fit "arm_wall"
Two plywood sides of 70x550 mm.
