I love 3D printed springs, and I wanted to include one in a carabiner for a while.

After few rejected ideas I came up with this (cool?) inverted spiral mechanism that acts as the spring for a carabiner.

I think it's pretty cool and wanted to share with you!

Also, the opening of the carabiner is designed in a way to stay firmly in place: the only way to open it is to push – it won't slide in any other direction than the one its supposed to.

3 sizes for the win: small (61mm), medium (76mm) and large (96mm)

Happy printing!
