I 3D Printed Carabiners

We tested PLA, ASA, and TPU filaments on a 3d printed carabiner with 25%, 50% and 75% in-fill. Then we tested 50% in-fill with 1, 2, 3, and 4 wall loops. 3-4 wall loops with any in-fill on PLA consistently got ~0.5kN or ~100lbs. All the other ones I wouldn't trust for anything.
