Strain relief device for the dell charger output cable which always seems to get damaged. This should be easily adaptable for any charger. I've included the blender source files.I found with ABS plastic the flexibility slots were the weak point, and once glued together it wasnt all that flexible anyway - you might want to start with the blender file without the slots cut and just halve and print that. I used hot glue to glue it together and to the charger. Theres enough room inside to fit some heatshrink etc if you have to repair frayed wires. Put plenty of hot glue in the end where the wire comes out for extra strength and strain relief. If you do have to cut the cable to repair it, I suggest you print the un halved version for extra strength - just slide it over the wire before reattaching.
