I'm just starting to mount my Honeycomb Storage Wall. I wanted a way to easily drill a hole that's centered in the hex for the mounting screw.

This drilling jig is meant to go into the cell that needs a screw hole to be drilled, you drill through it, then remove the jig (it does not have locking tabs so it's easy to remove). Then I push in the drywall anchor, then put in the mounting fastener part and screw that into the anchor.
