IKEA Bror Hole Hooks

My 3D Printer is sitting on an IKEA Bror shelf. It has a bunch of 5mm holes on the frame and I wanted to hang some useful tools on those holes. So, I designed these screwable hooks for that purpose. The picture is not that good, since the shelf and hooks are both black. I might add more images later, but from the slicer image you see how these hooks look like and what is included in the file. There's a couple of different options for the hook and nuts. This model in inspired by “Small hooks for multiboard”, and I wanted make similar threads to these screws, but I didn't know how. The standard 5M isometric thread works OK, but it's pretty tight.
