The file 'Fish Carabiner 3D Printer Model' is (STL) file type, size is 110.1KB.
This carabiner (which as I was recently informed is also considered the
"Jesus Fish") works. It can be scaled (almost) as much as you want up or down (don't go way too crazy), and the clip springs back as it does in a metal carabiner. It's a quick and simple print, and requires no supports or rafts.
