A simple 3-hole guy line cinch-up for a tent. I have a tent that uses a knot on the guy lines to tighten them up, I felt I could easily manufacture a model similar to the ones included with new tents. It fit my 5/32" nylon braided rope, as well as 550 paracord, but could easily be scaled up or down to fit your rope. cinch-up
I set extrusion at 0.1mm and used 100% fill. Probably could have used a higher extrusion rate, but I wanted as strong tensile strength as PLA can muster, so I put more layers in. Tough little guy does the job with ease!
