Basic Carabiner (Easy print)

There are many great carabiners on Thingiverse but I wanted to create my own. This is what I came up with. It's pretty strong (I haven't been able to break one yet) and has a nice spring action on the closure. I have only printed this using PLA. I think ABS might snap but not sure.

The model scales very well. In the picture, the smallest is 30mm and largest is 60mm. I'm sure you can scale it even larger and be fully functional.

***Obviously these are not for climbing! ***
