Linked square chain
by berserkerscientist, published
This 4 link chain will print as one piece. The links are about 10mm square, and 2mm thick. I was inspired when I saw this clutch (thing:31312). I'll probably chamfer all the corners, to make the links symmetrical.
I used 10% infill and 0.2 mm layer height, but this can be changed. I always use 230F nozzle and 110F bed temperature. Using a slower feed rate is better.
