Dimpled Fishing Float ••• aerodynamic, golf, ball, bobber

Fishing float with indentations.

Benefits of having dimples:

• Can be thrown farther (less drag)

• Gets pushed less by wind once in the water

• Looks cool

Open-source, fully customizable, parameterized, source code file included.  Created using ShapeScript.

Small note: I have absolutely no idea if it actually works 

Printing

Try to have less infill to keep it light, use supports.  To make it waterproof, either use thick walls or coat in a thin layer of epoxy resin.

As for the filament, go with something UV-stable; use clear filament to make it “invisible”… or even better — try something that glows in the dark!
