S-Clips for 2.5mm paracord/shock cord

These are S-clips designed to hold two loops of 2.5mm paracord/shock cord together. I've specifically designed them to clip my camping pillows (Klymit Luxe) to my ground pad base sheet (Zenbivy) using Zenbivy's backpacking quilt conversion. But I'd love to see your applications! 

These are rather small pieces, so I've opted to print them with a 0.25mm nozzle. They'll probably work just as well with a 0.4mm nozzle though.

I used a 0.25mm brass nozzle, PETG, 0.12mm layer height, 100% perimeters (6 walls should do the trick), no infill, no supports.
