Filter Cleaning Nozzle - Improved High Pressure

This is an improved remix of the popular Gardena pool filter cleaner, redesigned for significantly better cleaning performance.

The original concept is great, but several users mentioned the water pressure from the stock nozzle was too weak to properly clean filters. I noticed the same issue, so I redesigned the nozzle outlets with smaller openings to create focused high-pressure jets instead of soft water flow.
 

Improvements in this remix:
- Smaller nozzle openings for much stronger pressure
- Focused jet streams instead of weak flow
- Better dirt removal from deep filter pleats
- Cleans filters faster and more effectively
- Keeps Gardena hose compatibility
 

The difference is noticeable:
Instead of water simply “pouring” out, this version creates powerful concentrated streams that actively blast debris out of the filter.
 

Print recommendation:
- Print with the 5 nozzles facing downward
- Use a large 10–20 mm brim for bed adhesion
- 3 walls or more recommended for durability
- ASA or PETG recommended for outdoor use, but PLA works too
 

This remix is based on improving actual function, not just aesthetics — tested and tuned for higher cleaning pressure.

If the original lacked power for you, try this version.

Important:

This model requires a standard rubber O-ring/gasket on the hose connector part of the model to seal properly.
The O-ring must be installed on the connector tip where the hose adapter locks in. Without it, the connection will leak.
You can reuse the original gasket from your Gardena-style connector or use a compatible O-ring.

If you experience leaks near the rounded corners/nozzle body, increase the wall count when printing.
3 walls or more are recommended for better strength and improved water sealing.
