In my sump closet, water comes in from my RO/DI system, and is redirected to one of three locations. Mixing station refill, Kalkwasser reservoir, and ATO (Sump). From there, it goes through a set of 3 hand valves, one for each receiving point.

Leaves me with a mess of RO hose, and very few ways to tidy it up.

So... may I present, my 3 way RO/DI valve manifold :D

This is designed to hold 3 of the common 1/4" hand valves, banded in place with zip ties, easily mountable to just about any surface. Rev 3, the one photographed above, won't be done printing for another couple of hours, but Rev 2 kinda shows you the point...

In rev 3, I've made the slots a bit further apart, the handles were hitting each other in the OFF position, and I've cut some of the extraneous material from the sides. No reason for it...

Anyway, if anyone is interested in printing one, let me know, and I'll share a source file. It was done in F360, but I can generate about any format you might want.

Can I get the stl of f360 file? I often wondered why the valves don't have mounting tabs built in.
