Venturi water pump update for tube 50 diameter (this item not usable. designed new in my items)

Just remixed the venturi tube to fit in. Water tube 50 mm diameter - 4 mm walls, so 46 mm - 1 mm to go smooth. The second water hose connector, which will be attached to the pump. When I do all this, I will post a shorts about it on my YouTube channel. Fathercooking - welcome
And after printing this model with supports, the item was not usable because the supports couldn't be gotten from inside. Designed an absolutely new pipe, which was printed from parts / See my designs
