Works vertically or horizontally. Holes are at 22 1/2 degree angle. Stackable with aligned holes at top and bottom. You might choose to hot glue multiple panels together, or fasten them in another way. I designed this because I had too many narrow things lurking in my workspace that I use so often but have difficulty storing them properly. Pencil torches, small wire brushes, mini electric screw drivers, and so on. I just wanted tool up and out.

6" x 6" x 2" with 3/4" holes
