Description:
After using the original design on my keys for several months, I had to constantly reprint due to the pin breaking. The rest of the carabiner is incredibly strong but the pressure fit pin was a weak point. This design uses an M3 nut and a M3 socket head screw to replace the pin for added durability, and reliability.
