## Step 1: Design the Crankbait

I designed this crankbait in OpenSCAD. Posted is the code i used:

\$fn=10
0;

translate([0,-.5,0]){

rotate([-90,0,0]){

difference(){

union(){

hull(){

sphere(.5);

translate([.4,0,-.05]) sphere(.4);

}

hull(){

translate([.4,0,-.05]) sphere(.4);

translate([.7,0,-.15]) sphere(.3);

}

hull(){

translate([.7,0,-.15]) sphere(.3);

translate([1,0,-.25]) sphere(.2);

}

hull(){

rotate([0,-25,0]){

translate([-1,-.25,0])

cube([.8,.5,.03]);

translate([-.8,0,-.1])

rotate([0,90,0])

cylinder(.8,.06,.06);

}

}

}

translate([-4,0,-2])

cube([8,8,8]);

translate([.06,0,-.025])

rotate([0,-76,0])

cylinder(.6,.07,.05);

translate([0,0,-1])

cylinder(1,.07,.07);

translate([2,0,-.51])

rotate([0,-76,0])

cylinder(2,.07,.07);

translate([.175,.10,-.3])

rotate([90,0,0])

cylinder(.35,.1,.1);

}

}

}

translate([0,.5,0]){

rotate([90,0,0]){

difference(){

union(){

hull(){

sphere(.5);

translate([.4,0,-.05]) sphere(.4);

}

hull(){

translate([.4,0,-.05]) sphere(.4);

translate([.7,0,-.15]) sphere(.3);

}

hull(){

translate([.7,0,-.15]) sphere(.3);

translate([1,0,-.25]) sphere(.2);

}

hull(){

rotate([0,-25,0]){

translate([-1,-.25,0])

cube([.8,.5,.03]);

translate([-.8,0,-.1])

rotate([0,90,0])

cylinder(.8,.06,.06);

}

}

}

translate([-4,-8,-2])

cube([8,8,8]);

translate([.06,0,-.025])

rotate([0,-76,0])

cylinder(.6,.07,.05);

translate([0,0,-1])

cylinder(1,.07,.07);

translate([2,0,-.51])

rotate([0,-76,0])

cylinder(2,.07,.07);

translate([.175,.10,-.3])

rotate([90,0,0])

cylinder(.35,.1,.1);

}

}

}

I designed it to have a thin gauge wire frame to attach the treble hooks and split ring. There is also a hole to put in a bb or two to create a rattle.

## Step 2: Print the Crankbait

I printed this .stl file that was exported from OpenSCAD.

I printed it with supports and a raft at medium Resolution.

## Step 3: Use the Crankbait

On my second cast with this crankbait i hooked a fish, and as i was reeling it in another one came and got hooked two, and right as i got it in, the first one jumped off.
