Description
PDFI wanted to design a print-in-place catenane that requires no support so here it is! Prints well in PETG.
I am sure there is a way for making this via injection molding, but I think it’s a cool print that leverages the strengths of FFM. It’s also really fun to fidget with, if that’s your thing.
