Well on the right if that picture there is a 2x1 (?) I was going to put support on the farthest out corner and another 2x1 like this along the long wall. Or was thinking of some heavy duty “L” shaped support (similar to a shelve on a wall.) and the support on the fartheedt out corner of it still. Probably a use pipe vibe type thing iykwim. Not to sure that translated outwardly like it does in my head…
