About this 3D model

This is my magnetic and “modular” cat key rack/key holder. I used 3M double sided tape for mounting (use more as I did in my test picture) and a 12mm neodymium magnet with a holding force of approx. 2kg. Cat size is approx. 97x85x4,3mm Circular cutout for magnet is 21 x 3,2mm Use 5 bottom layers for an even color.
