Like the previous Morse leaf chain, this chain is designed to be even more simple by press-fitting the pins on the outside segments. The segments can be arranged to use a single or double sprocket. The single sprocket design uses the normal pins while the double uses the long pin. I have not tested this design, so please post any feedback in the comments. If you do print this, I have included various files with different quantities of each item to match print bed sizes and printing needs.
With regard to printing, note that, for any chain, there is a 1-to-1 ratio of clamp segments, (which press fit with the pins at their ends, and middle for double-width), and mid segments (which rotate freely around the pins).
