I was doing some work in the garden and while I was using the electric grasstrimmer I stepped on the cord all the time, yanking the plug out....so I made this simple restrainer to mount on the cord....problem solved.I've added hexaon pockets in the STL for M3 nuts and 3.2 holes for two M3 16 or 20 mm bolts, clamp it on your tool and "tie" the extension cord like you see in the pictures. Go crazy on your grass and cord :)
