Venturi injector

This is my first attemp to make a venturi injector to add chlorine and other chemicals to my borehole water

Printed and tested with the default full stl design it works like a charm on a borehole pump connected to a 3/4" pipe to inject chlorine to the water flow with a 5mm PE tube.

Printed with 1mm wall and 75% infill in ABS using 8mm brim and support on touchbed only print perfectly and it's able to manage pressure up to 6 bar without leakage.
