Description
I designed this to mix a small amount of liquid fertilizer into a stream of water from a garden hose.
I have a worm composter that produces quite a bit of liquid fertilizer and I wanted to dilute it and sprinkle it on my lawn.

Instructions
Print it out.
Break out the little support cylinder in the bottom and cut out the think membrane over the hole.
Place a rubber washer in the female threaded end.
Tap the vacuum port with a 1/8 NPT tap (don't force it and crack the plastic)
The hole is already tapered so hopefully it shouldn't be too much work to tap it.
Insert whatever 1/8" npt fitting you want into the port (JG fittings are nice)
Hook it up inline with your sprinkler or whatever.

Very nice! I've been waiting for a printable venturi something or other. Not that I need one, but it seems a natural thing. Actually what I really want to see is a printable vortex tube for cooling, now that'd be fun...
