2x4 Wall Shelf bracket

Left and right bracket that allow you to build a wall shelf out of scrap 2x4 pieces.

At 20% infill the brackets are quite solid when used with 11" long pieces of 2x4 lumber, it can easily hold 25 lbs speakers when mounted on drywall with toggle/wingnut type bolts as fasteners.

Printed under "draft" settings on my Thinker SE with a Triangle Labs Matrix extruder, no supports needed, I used a brim but my bed isn't perfectly flat.

Assemble with 2x4's, then square the assembly, then drill/screw the pieces of wood using the holes underneath to fix the pieces in place,

Let me know if you need more info.
