This shelf bracket is perfect for holding an Openlock style base and wall. I designed it with the intent of creating a wall diorama of Openlock tiles where I can display various D&D and Warhammer models. While the diorama is incomplete, the shelf brackets work great.
Mounts fine with standard 1.5" sheetrock screws. Smaller screws would look nicer, of course. I'd also recommend printing in a dark grey or brown to fit in with the painted tiles or in the same color as your wall.
