I designed these simple flat carabiners to store and organize Rubber O-Rings. They are not meant for heavy-duty use, but they work perfectly for holding light parts together.

I’ve uploaded a bunch of files with different sizes. In the filenames, the "mm" number stands for thickness, and S/M/L refers to the approximate size. PLEASE NOTE: Size "M" is different for different thicknesses! You can see the size comparison in the third image (Blender screenshot).

Honestly, I recommend just scaling the thickness or size to your liking in PrusaSlicer (or any other slicer).
