Ejector Venturi Gardena

My attempt to make an ejector which would inject soap into the water stream to be used example when cleaning house or car.

Its designed to use 6 OD hose to inject to soap, my plan was to further develop it if it worked to directly take example an 1/2 soda bottle.

Feel free to try and improve design, original Fusion 360 files can be downloaded at this link https://a360.co/2FaDaya

Please post remix if you make it be
