Double Tesla Valve with shower thread

This is two "Tesla Valve"s by toehead in reverse directions with a thread at the end. The thread is from the "Post-modernistic-pre-futural-or-so shower head with handle" by docpayce. It fits a european standard shower hose.
toehead says: "Works marginally well." I can confirm :-)
Maybe you should try to print it with high resolution (small nozzle).

You might want to print it "standing".
Have fun!
