Easy chain
cults3d
Very easy chain to print and make. The STL only has one link. Import it into your slicer and change the size and then duplicate it for how many links you want or fit on your bed. When linking them together push the links together using the gap section turn the new link around and add your next link. I have found this fool proof and never fails. If you are worried about it coming apart you can put a spot of superglue on the gap.
