Fixing The Estes Launch Controller, Part 3

A comment from the Estes Controller Fix posts:
"Have you considered opening up the hole in the end of the case, and adding a short section of heat-shrink over the wires as they come out of the case for a little extra stress relief? Don't know if it would work, but it sounds good anyway!"
Sincerely,
J.W.

An email from Brian Coyle,
"Saw your post about fixing the Estes launch controller.  Reminded me of this USB hack & I wondered if it might help reinforce the cable where it enters the box.
To see the article: CLICK HERE
Since you are removing the cable from the terminal, maybe even a section of heat-shrink tube could be added. (Alone or over the spring)"

Thanks Guys!
For the heat shrink to work it would have to extend into the exit hole in the plastic controller box. That would involve making the hole diameter larger. Not a problem to enlarge the hole. There is just no room inside the top of the controller for a little of the shrink wrap with that strain relief knot tied in the wire.
But, the spring might work if the end were turned into the hole -
