Tarp Clip Remix

This is a remix of https://www.thingiverse.com/thing:4139704

I really liked the design, but I added some tabs to keep everything aligned, a little bit of extra clearance on the M5 nut handle, and I also put a spring in between the sides to push them apart when unscrewing. My goal was to make these tarp clips as one-handed as possible to make hanging tarps and such from other tarps easier.
