Made to mount on the side of a Ikea Lack enclosure with 4x #8 C/S screws, it will hold a razor blade, 8 nozzles, 3 cutters/pliers, 3 hex wrenches (2.5, 2, & 1.5mm), 2 nut drivers, tweezers, a marker, a small spritzer bottle, a wire brush, and a cloth.
Supports only needed for mounting tabs on rear. Adding a "support blocker" on the bottom 2.4mm of the part kept the supports only where I wanted them.
