This is a modified version of the chainsaw chain made by the lovely gbit which was in turn a modified version of the roller chain made by Gedgey.

Unlike it's predecessors, this version is designed to be 3d printed. I printed it at 0.2mm resolution, and it fits together just fine without needing glue.

Like the design that came before me, I won't even attempt to explain how to assemble it with words, and instead I will use Tinkercad screenshots to show how all the parts go together.

I printed this design with a tooth on every segment, in the style of a Warhammer 40k chainsword. If you want to have some segments without teeth, or even just print it without teeth entirely, I have included a chain segment without a tooth on it.
