The Subatomic Sprinkler | Gardena Compatible

Subatomic Sprinkler | Gardena Compatible

The Subatomic Sprinkler is the result of 70+ test prints , dozens of geometry tweaks, and a mission to create the most efficient ultra‑light sprinkler possible. Despite weighing around 7.82 grams (PETG), this print‑in‑place design delivers a surprisingly powerful spray.

Designed for people who want performance without wasting filament, the Subatomic Sprinkler works straight off the printer with the correct O‑ring and snaps directly into the Gardena/Quick Connect system.

🌊 Performance

- Fixed jet stream with considerable range depending on home pressure - Realistic max reach: ~15 ft / 4.5 m (single stream, NOT FULL COVERAGE) - Efficient even at low pressure — great coverage without overspray 🧩 Design Features

- Print‑in‑place — no assembly required - Ultra‑light: 7.82 g (PETG) - Perfect for using the last bit of filament on a spool - Tuned geometry based on 70+ iterations to improve spray uniformity (still not perfect) 🖨️ Print Settings

- Layer height: 0.2 mm - Infill: 15% gyroid - Walls: 2 - Supports: None - Material: PETG, ABS, or ASA recommended - PLA works only in cool conditions (avoid sun/heat to prevent warping) 🔧 O‑Ring Info

Use the standard O‑ring for the Gardena Connector (Outer Diameter-16mm, Inner Diameter-11mm)

🌱 Use Cases

- Lawn & garden watering - Pressure‑adjustable coverage: lower pressure = smaller area - Great for quick setups, or targeted zones 🔄 Upcoming Variants

Depending on how well this model does, I will be experimenting with:

- 180° variant for semi-circle coverage - 90° variant for corner watering - Custom cone slope and bore variants upon request - The current model is 360_35_0.25 (Which means it sprays in a circle, exits the the deflection cone at a slope of 35°, and the exit ring/opening is 0.25mm wide.
