Description Files

Summary

This is a robust 3D printed carabiner with higher load capability and better gate function than most other 3D printed carabiners out there.

Obviously these are not for climbing, they are plastic. If you depend on this carabiner to save your life from a fall, you will probably die.

v2 - Improved version with better gate:

More reliable, longer lasting, easier to assemble and disassemble. Modified frame profile to minimize overhang. Now with 3 different carabiner sizes provided and original Solidworks files.

Features:

Design based on wire gate climbing carabiners to maximize strength and utility
Preloaded gate tension for reliable closure
Hook latch so gate will not pop out under load
Major axis pushed close to spine for maximum strength under load
Easy to assemble, twist-lock gate assembly
Fast and easy to print, no supports, no intricate features

I have load tested these and they are surprisingly strong. With PLA and 50% infill it has a breaking force of over 150 lbs. With 100% infill it is over 300 lbs; in fact I couldn't get it to break because I didn't have enough weight. Let me know in the comments if you can break a solid one and what it took.

Carabiner Frame Dimensions:

Small - 70 x 40 x 5 mm
Medium - 92 x 52 x 6 mm
Large - 134 x 74 x 7 mm
