This is a simple and effective blind plug I designed to seal the outlet for the foot shower on our outdoor pool shower. The original tap started leaking, and since we never really used the foot shower anyway, this was the perfect solution to fix the leak without replacing the entire fixture.

The design includes a recess for a gasket to ensure a watertight seal. Just reuse the gasket from the old tap or use a standard o-ring.

The thread size for this plug is M20x1.0. However, the included Fusion 360 file is fully costumisable, so you can easily modify the thread size and other dimensions to fit your specific needs.

Printing Recommendation: Use ASA for its good UV resistance. PETG or other durable materials may also work, but keep an eye on longevity.
