There's only so many things that can be written about a shower head, but here it goes. :)

I wanted something similar to the one we have already, which is breaking down. So made it in a simplistic (IMHO) shape. Made a few attempts, the first ones had too many holes and the force of the spray was not satisfactory. I might make a few more versions, but more or less satisfied at this point. Potentially even further reduce amount of holes/radius. If anyone would like to modify further, also attaching the Fusion 360 file. 

It fits G ½ standard threads. My first print was water proof by the threads directly, but 2nd print I needed to put some plumbers tape around the threads to have it water proof, but it should be a close fit either way.

I printed it with the threads facing up, so on the short flat side. To minimise risk of it tipping over I printed with a 10mm brim. Also used variable layer height to get some finer detail around the holes and for the threads, without making the print too long. 0.2mm layer height, printed it in Add North's HT PLA Pro Matte which has a higher tolerance to heat. 

That's about it I think, happy showering! :)
