The plan was to build a better strain relief into the Cord using first a spring from a ball point pin and a package of Sugru.
Step 1: Prep
1 Ball point pen
1 or 2 5g packs of Sugru color is up to you.
Step 2: Build
Carefully wind the Sugru around the plug and down to cover the spring, I didn't press the Sugru into the coils of the spring as I wanted the cord to move independantly of the spring. Shape the Sugru to your liking making the connection to the cord and the plug body.
