Having got wet more than once trying to operate a site tap and make sure the hose didn't flail around, I've been meaning to buy one of those Heoswater caps for a while. It would appear there is a cheaper one around now, the Haba Rheinland, which Homestead in Essex list at £6.99. They were out of stock on Tuesday when I was there but I came across this - - which looked as though it would do the job.
I printed it yesterday in basic black PLA. It took about 6 hours to print but watching it doesn't make it any faster, so I just left it to get on with it. I fitted an O ring from the spares box and tried it out - success!
It isn't at all tight on the fitting on the side of the van, so doesn't seal. In reality it doesn't need to, as long as the water flow is directed successfully down the filler pipe. I squashed a short piece of half inch hose on the back just to avoid any possibility of 'blowback' but the design is for 15mm hose, which I don't have 'in stock'. I didn't fill the tank to the top so don't know exactly what will happen then. Our van has an overflow pipe underneath but it can't flow at the same speed as the tap, so I expect it will spurt out of the two holes in the cap, so I can still expect to get soaked if I'm not careful!
To be honest I didn't come across many other useful things to make for the van, though I'll probably print a few coat hooks for the garage.
If I'd found this design a few weeks ago, I could have made a few for the Bring and Buy Rally and perhaps be well on my way to my first million! However, I wouldn't have been able to guarantee they were made from food grade plastic..........
