Snap cable wrap for charging cables
Charging cables knot in a bag unless something holds the coil, and a rigid wrap works better than a velcro strap that sheds fluff. The wrap is a 50 mm oval spool 8 mm thick with a 20 mm central core, two 6 mm side notches that snap onto a 3.5 mm cable, and a 12 mm gap at one end for the plug. Rounded 1.5 mm edges stop the jacket getting nicked, and TPU or PETG give the notches enough spring to hold.
SpeakCAD sizes the notches to your cable's exact jacket diameter, from a thin 3 mm USB-C lead to a chunky 6 mm laptop cable, and scales the spool for the cable length. Add a lanyard hole or your initials in the chat and preview free in the browser.
