A replacement for Loop's flimsy plastic case with a key ring or string attachment. The hoop carrier was designed to fit a S-Biner MicroLock. The String carrier should take paracord but not tested.
Wayyyy better than regular case, printed in PETG but got some quality issues at my own fault, I'd probably go for a PLA Pro if I did it again. I really like the included bump to tell which is the top and it's easy to get them in and out.
