This lure Prints in one piece and has multiple hinged segments that loosen up once the lure is bent back and forth a few times. This gives it a swimming action and it has internal chambers for adding metal bbs for rattles.This lure prints laying flat on its side, using support. Once printed, the support can be cut off and once the lure is bent at the joints, they should loosen up.I used a standard 15% infill with internal bbs for rattles and the lure sank at a nice gentle rate, but you could probably experiment with different infill densities to alter the rate of sinking.
