This is a simple cable handler/organizer to pack long and heavy cables.
You can use a little bit of rope as I did or anything else (shoelaces ecc ecc).
Just roll the cable, make the rope through and then above the printed piece and your cable won't unwind itself, also you can hang everything wherever you want.
PRINT SETTINGS:
Filament: Printed with PLA but can be printed in ABS/PETG for heavier cables
Layer height: 0.2 mm with 0.4 mm nozzle
