Carabiner - Karabiner

works, although this locking mechanism does not provide strenght by actually holding the arm when applying load

Does the job!

Works perfectly to hold my filament swatches!

I tried printing it at 40%. While the mechanism still works, the mantle part is very loose, since the latches are only one wall thick. So for this small size that part would probably have to be redesigned a bit thicker. Otherwise I like the idea and even at this scale it is very strong once closed.

Thanks for sharing
