High Load Carabiner

I was tired of how flimsy the ddf3d carabiners are so I came up with a high load model optimized for easy printing. I did keep ddf3d's gate lock though with a minor change to keep the inside surfaces from fusing during the printing process. No supports are needed to print this.

I have not tested this to breaking, but only because I ran out of weights. printed with PLA I was able to lift 50LBS with no damage to the carabiner. If I had to guess I'd say it would probably fail at around 80-90LBS with 30% infill.

This was modeled with a climbing belay carabiner in mind for both strength, and room inside the carabiner for rope/load. However, DO NOT use this for climbing, or overhead lifting.

If someone has the equipment to test the tensile strength of this I'd love to see your results!
