shower head replacement part

OMG it's a shower head replacement cap. Just imagine how grateful mother earth will be if you print it instead of buying the full shower kit. Print it now and save the world. I'd buy that for a dollar !
P.s. before you save the world take in mind that you will also need to print the gasket part out
of Tpu or similar material or use the old one or remember the dark times and cut the gasket out of rubbery stuff with your bare hands!
