Simple magnetic cable organizer with screwed caps to allow a variety of cable widths. I attached it on the wall using double sided tape. The provided stl and step files are suited for 6x2mm neodym magnets and up to 3.6mm wide cables. I added the source Fusion 360 file, which is parameterised to allow you to modify the magnet and cable sizes.
v2: More thread clearance, now with wider cable support (3.6mm)
