I was in need of a fix for a leaking shower faucet at the base of a tub in our camper. So I learned how to print TPU after modeling this gasket. It goes between the water fixture and the tub to prevent leaks just from water standing on the sides of the tub. 

I did print it at 15% infill ONLY because I want it to be able to flex/sandwich once installed to behave like a true gasket.

Works for industry standard faucets in campers. Such as the bathroom shower/tub or sink. 

Let me know if you have questions! :)
