This is a remix of the antenna winder by K6ARK. I've added some holes for wire and guy lines. It will work as a sliding tensioner for guy lines.
This is part of my every-day-carry setup. It replaces the buddipole winder that I use for my counterpoise. I use it for Parks on the Air quite a bit. It can easily hold at least 33 feet of counterpoise wire. I haven't tried any more than that.
I also use it for guying my Buddipole mast. There are holes to accommodate 3mm Mastrant guy line and will allow you to slide it to tension the line and then have it remain in place.
There is also a hole for an s-biner or similar.
This winder loaded with counterpoise wire is 0.9oz./55g lighter than the similar buddipole winder setup for both PLA and PETG.
