Printable Cable Drag Chain, with 16x12 internal dimension. 45 Degree rotational limit per link for radius limiting.
Suits standard 2 and 3 screw cable chain mounts, with inverted variants to mount either direction.

This chain is designed from the ground up to be completely printable with no supports. I recommend at least PETG if using externally, preferably ABS/ASA. ABS/ASA heavily recommended if using in a chamber.
