Simple Carabiner

I was missing a good carabiner on Printables. So this is the simple carabiner by Daniel Brekke made available here from Thingiverse

NOT FOR CLIMBING OR SAFETY CRITICAL APPLICATIONS!

The .STL files are available for full size as well as 80%, 60%, and 50%.
For best results, print with the following wall thicknesses:

Carabiner= 8 walls thick (IMPORTANT FOR SOLID SPRING BELOW SLOT)
80%= 6 walls or 2.4mm
60%= 5 walls or 2.0mm
50%= 4 walls or 1.6mm

Gate= 10 walls thick (IMPORTANT FOR SOLID CENTER SPRING)
80% gate= 8 walls or 3.2mm
60% gate= 6 walls or 2.4mm
50% gate= 5 walls or 2.0mm

Printing with less than these wall thicknesses may result in fatigue cracking of the springs.
3 top and bottom layers work great.

The approximate sizes are:
100%= 107mm
80%= 86mm
60%= 64mm
50%= 54mm
