Emergency Shower head

well, i thought i would have a nice day off with it being a bank holiday in UK... should have known better..

climbed in the shower, the last one to get to it, a few minutes into my shower and the shower head pops off! bleeding kids... so after i finish my shower holding the pipe above my head i went out to buy another..... bank holiday, nothing open local

so in keeping with the RepRap ethos i knocked this one up to keep everyone happy till another arrives via eBay
