About this 3D model

I currently have no separated "workshop area" and I got tired of my feline friends obliviously knocking over cups filled with tools or utensils. These were designed to screw into something and stay put. They seem to work for that purpose. Scissors, pliers, markers, needle files, etc. I put holes into cheap bookshelves, but I have the ease of access to my stuff and I haven't found them scattered on the floor since.
