This shelf lets you store up to 10 Dymo D1 labels neatly on your Honeycomb Storage Wall.

It's designed to attach to the wall using M3 screws and a threaded insert.

You can use these inserts to heatset threads in to screw into.

I screwed them on lightly, pressed the whole thing into the wall and then tighten them - but you could also just put them in the grid and then screw the shelf to them.
