Laptop cable repair
Here's a clever Plastimake solution for a damaged laptop charger cable:
A cable on my Dell notebook was frayed due to it being a (stupidly) straight cable and constantly being bent.
Once it stopped working I resoldered it and rehoused it by wrapping it in Plastimake and formed it into a right-angled cable to keep it from getting bent. Here's the finished moulding, it was later finished off with some heat-shrink to cover it up.
