Well, it's that time of the year when we like to go Camping, and after a smelly evening in front of a BBQ and spilt beer we need a shower, right ?. So off we go to the shower block and into the shower cubicle, to be faced with a push vavle on the wall that gives you enough water to water a small plant, before it pops out and off we go again - press the valve and another small dribble of water appears, it's enough to give you RSI. So, print this little device that I designed, slip it over the valve, twist to lock it on, this will lock the button in and hey presto - enough water to fill an Olympic swimming pool - just don't forget to remove it when your skin has gone all wrinkly and you have finished. Enjoy your showers from now on !
