Carabine stress test

So i came over this carabiner on thingiverse. After comments by some fellow students that they would not even trust their water bottle to the contraption, it got me interested. carabiner-stresstest

I went home to print one with 80% infill, and here is the result. After some improvising at my local gym i got it to carry 40kg of weight.

It hang there for about 5 minuts until it suffered from fatigue and broke.

After the surprising results i had to print one with 100% infill. Though it did not result in an improvement.

Do you want to print your own?

You can find the design here.
