3D printed topwater popper style fishing lure with dual treble hooks and internal rattling ball bearings. The cupped mouth creates surface disturbances when reeled in, mimicking the movement of injured prey. The body is coated with paint and glitter under a clear lacquer which create a watertight seal and reflects light to mimic fish scales.
T-spline modeling was used to shape the body of the lure. Through holes were added to accommodate wire running through the body which securely attaches split-rings and hooks. Indents were also added for inset glass eyes. The concave mouth was iteratively prototyped and tested to identify designs which create splashes and disturb the surface of the water for both slow and fast retrieve rates. Designs which caught the most fish were selected for further development.
The lightweight body has hollow internal chambers to make it float on the surface of the water even when reeled in. The printing process is paused midway through to allow ball bearings to be inserted into the chambers. The BBs rattle to make sound and provoke strikes by arousing the attack instincts in fish.
