I made this organizer for my office to keep my ethernet cables organized but also accessable via the magnetic lid. It works well for cables under 6mm in diameter. I printed it at 100% infill and since it is a small part, it didn't take long to make. I used a ½ inch screw to attach the lid and a dryway screw to attached the organizer to the desk/wall. I also used 2 6mm x 2mm magnets, one for the lid and one for the base.

Ennjoy!
