Cable reel organiser.
I designed this to stay in the middle of the cable, so that the ends tidy up more consistently.
The lid snaps in place, but still easy to remove.
Prints in separate pieces.
The short one was designed specifically for the USB-C from my phone, and the tall one for the cable of a macbook. Both use ~3.8mm cables.
The lid is the same for both types.
Update 4th Feb: Updated the tall container model to include a missing chamfer that was stopping it from working! Thanks for the catch, managed to ruin it cleaning up the chamfers!
Update 6th Feb: I have removed the cutouts that made the tabs on the core, there is still enough compliance for it to work, but hopefully this addresses the concerns about tab strength.
