Backflow preventer valve replacement

Warning:
I do not recommend using this model for repairing a system that is needed to meet any kind of standard. There is no guarantee that this will repair your system properly. Use this model at your own risk.

I printed it with .6mm nozzle, 4 walls and 100% infill, PETG

Update: I have it print in 2 parts with an alignment ring for gluing.
