Simple shelf brackets with access holes for screws.

Surprisingly, I did not find a bracket on Thingiverse (where this was originally posted) that I was quite satisfied with, so I designed my own.

The access holes are enlarged to allow for easier tool access. The shelf board screw holes are counter sunk and sized for the specific screws I was using when I created the bracket. The wall screw holes are counter sunk with a tapered fastener head surface to fit the exact fastener head shape and size I was using to install the brackets to the wall (concrete block behind drywall).

The regular bracket has an offset for the shelf board so that cables can be fed behind the shelf board at an exact depth requirement for a cable on my shelf.

The "no gap" bracket has that offset removed. The rest of the bracket is identical.

Dimensions with bracket oriented as it would be installed on the wall:

Depth: 126mm

Height: 120mm

Width: 20mm

Offset depth for applicable bracket: 16mm

Wall mount hole diameter: 5.5mm

Shelf board mount hole diameter: 3.75mm
