Pool Nozzle circular movement

I designed this pool nozzle to create a circular flow in the pool, which keeps the water moving away from the inlet. Even with a small pump, the nozzle sends water in one steady direction, creating a circular current that flows around the pool.

This movement helps guide dirt and debris toward the pump, making your filter pump more effective. Make sure the outlet nozzle is installed so that it faces away from the inlet nozzle. This setup helps the pump pull in dirtier water instead of just recirculating the clean water.

The design works especially well in round pools, where the circular flow can move more easily.
Additionally the nozzle is designed with rounded edges so is safe to swim and play around.
Use ASA as material so the nozzle is UV resistant.
If someone has experience with other materials feel free to post it in the commenting section.

I attached 3 different sizes of the nozzle in the print profile.
Currently using a 15mm Pool Nozzle with a 10000 l/h pump and are very happy with the result.
