I always need a few of these in my truck for securing items!
Two options for the end, either a hook or a loop. Works great with paracord and should work with thicker cord or rope as well.
I recommend printing in PETG if you are going to keep it in your vehicle or use it in the sun.
It has not been weight tested but seems very strong. I plan on using it to secure a hammock and yolo it.
I CANNOT STRESS THIS ENOUGH, THIS IS NOT FOR CLIMBING!!!! USE AT YOUR OWN RISK.
