Ok, this is pretty cool. This is one of the reasons I'm convinced that 3d printing has a huge potential.
I would love to see real community developed things like this especially that can adapt something as simple as a 2L soda bottle into a pretty cool protein skimmer.
Imagine if we had plans online for media reactors, calcium reactors, other parts (barb fittings, etc) that you could easily get access to and start building at will.
Anyway, thought the DIY minded crew here would enjoy...
