About this 3D model

Hi, I made this thing before: https://makerworld.com/en/models/80119 Although I wanted something more customizable so I made this system to replace the old model. For now there are various attachments: Hooks, Bins & Hooks. This set works on garage shelves with: Holes: 12mm upper 7mm lower Metal Thickness: 1mm Distance between upper holes 32mm Example Image of dimensions: If you want to create your own attachments the width of the mounting piece is 30mm, the cylinders that slide in are 4mm in diameter and 15mm apart. Or if you want something specific ask and I'll give it a go. This is seems to be pretty sturdy and I can hang a 1kg filament roll off the large hook as a test. I'll probably make more attachments and upload to this over time.
