Bottle Shower Cap – Screw-On PET Bottle Sprinkler

Bottle Shower Cap – Screw-On PET Bottle Sprinkler

Turn any PET water bottle into a portable shower. This screw-on adapter replaces the bottle cap: fill the bottle, flip it, and water sprays through a closed perforated head for a real shower effect—no open cup that just pours.

Features

- Female helical thread designed for common PET bottle necks (~23.3 mm smooth neck OD) - Closed shower face so water exits only through the holes (not over the rim) - Slow-flow version with Ø1.2 mm holes for longer use and gentler spray - Compact print: ~48 × 48 × 19.4 mm - Manifold, watertight mesh ready for FDM Print tips

- Material: PETG recommended (water contact); PLA OK for light/short use - Orientation: flat on the threaded base - Layer height: 0.16–0.20 mm; for clean Ø1.2 mm holes prefer 0.12–0.16 mm - No supports needed - Walls: ≥3 perimeters for strength on the thread Use Screw onto a compatible bottle, fill with water, invert, and squeeze gently if needed. Ideal for camping, beach, garden rinse, or pet washing.

Note Bottle threads vary by brand. If it doesn’t screw on smoothly, measure major diameter and pitch—happy to help adjust.
