Magnetic Cable Clip

The STL file here is made to fit a 3mm wide cable and a 10mm diameter x 5mm thick magnet with a 0.1mm gap all around the circumference of the magnet. The model in the pictures is for a slightly different size magnet which I haven't uploaded the STL for. If you have different size magnets, different size cables, or require a different tolerance you can download the Fusion 360 file and change the parameters. My magnets hold tightly with just friction but you can glue them in if they won't stay in.
