Pool solar cover clamp

A clamp replacing original item for pool solar cover winder I made this because original items were breaking apart.Maybe someone will find it useful. Print instructions:Top and Bottom parts:At least 25% infillUse PETG or something more temperature resilliant. Note on material:In my experience PETG will bend under heat over time to a point it will lose grip (see picture after 2 months of use).I will have to wait until next season to see how ASA and ABS handle those same conditions. Back part:I used TPU, 15% infill works. Assemply instructions:Slot together Top and Bottom item on the solar cover, then place the back item, push through the rope and make a knot.
