These shower heads work well in places where you're restricted vertically. Can be mounted flush to the ceiling on top of shower rail using shower hose extension.

Water flows out at 15 degree angle forward.

Printed with PETG at 150um. Make sure to add 20 vertical & horizontal walls to ensure water tight.

No leaking between layers in my print however you could clear coat with epoxy.

I use the 150mm version, I never printed the larger ones but included as an FYI.
