DIY micro sprinkling system for Gardena 4.6mm

This is a set of functional garden micro-sprinklers and connectors designed for 3D printing in PETG. These components are intended for watering small areas—such as rows of vegetables or grouped plants—rather than classic drip irrigation.

Key features:

• Printed in PETG for outdoor durability.
• 4.6 mm inlets, compatible with Gardena Micro-Drip 4.6 mm tubing (important: not compatible with the larger 13 mm Gardena Micro-Drip hoses).
• Compatible tubing: Flexible 4 mm hoses (e.g. commonly found on Amazon) can also be used, but are more prone to leaking due to material and/or fit tolerance.
• Design aims at straightforward prints with minimum waste.

Currently included in the collection:

• 30° Micro-Sprinkler
• Straight connectors for 4.6 mm tubes
• T-connectors for 4.6 mm tubes
• Gardena hose adapter to 4.6 mm (1 output)
• Gardena hose adapter to 4.6 mm (4 outputs)

You will need :

• Gardena 4.6 mm tubing
• Gardena 9 mm o-ring for the adapter
• Tube holders -- My personal recommendation is to self-print these (but you could also purchase) !

Coming soon:

• 45° Micro-Sprinkler
• Gardena hose adapter to 4.6 mm (2 outputs)

⚠️ These components are compatible with Gardena 4.6mm Micro-Drip tubing (not 13 mm) but are not pressure-matched to the original system. They are meant to spray small surface areas rather than provide drop-by-drop irrigation.

Perfect for makers who want to customize their garden watering setup and experiment with printable irrigation components !
