This is a printing experiment for movable parts. The chain is printed in one single piece, therefore, the chain elements are already linked when printed. And it of course moves. For demonstration and/or customization purposes, I also added the single chain element but if you want to print the chain, you just have to use the STL with the 10 chain elements. I printed it laying flat on the bed, with raft (difficult to remove) and support, touching the build plate.
