Print upright using as many walls as will fit, or concentric infill at 100%. Run your filament hot to make sure you get good layer adhesion to prevent water intrusion. Larger hookers and jig-heads may catch outside of the chamber, but should still be safe as the hook will be pressed against the bopper and not able to snag anything.
Use with any bobber-stopper (one available on my page) recommended.
Happy fishing.
