Who said we couldn't print useful things? Here's a flat-pack modular rotary hydroponic unit to be produced by most CNC tools.
My Blog Post about this here: http://engineeringourfreedom.blogspot.com/2011/05/do-cartwheels-feed-people.html
For working examples of such a system, see OmegaGarden.com RotoGro.com or H2ODynamic.com
Call it the ModRotoHydro, RapFarm, FeederBot, Farm@Home, or whatever else you like, I don't care, just help me build them and feed the world. ;D
Some bits of the assembly are made from or based on standard mendel parts, such as the frame vertex and Prusa's Y-bar clamps. The current gear-tooth profile is based on http://www.thingiverse.com/thing:8077; I might try a version with an easier-to-print zigzag, though it may be less efficient.
The cylinder has an outer diameter of 1 metre, ID of 80cm, and the trays are designed to hold 75mm/3" rockwool cubes, though it would be very easy to design alternate holders for smaller sizes.
