bottle to 1" adapter

The main use of this adapter is in the area of low pressure hydraulics. I designed it to be able to attach a filter to a DIY venturi pool vacuum, however it is possible to use it to enter nutrients in irrigation systems or even as a water quality viewer or sprinkler.
The measurements of the threads are M33x3 for the outside and M28x2 for the inside. The internal thread is compatible with any soda bottle and the external one with 1" connections.
