The impeller from http://www.thingiverse.com/thi... will work for this design, It allows you to use a standard hobby motor with a 2.25mm shaft.
better off using a pelton wheel design in most cases for micro-hydro.
There is one here http://www.thingiverse.com/thi...
I used motor from Lexmar Ink-jet printer (it is one that move printing head left-right). You can find such motors in Lexmark Z25 and similar and 510 series. I also think that in many other series of printers by this company motors are the same (many times they just change design without any changes inside and sell as new model).

I also attached adapter for motor that I have in file "Motor Gear Connector (Sliced) - 2.STL". Print two parts and connect together with two M3x16 bolts and nuts, put inside single M4 nut to be used for turbine connection.
Turbine top cover has end that fit just fine 30 mm pipe adapter designed here: thingiverse.com/thing:39745 and was done to be used together with it (take some time to see how and where it can be used together with this adapter).
Note: In some .STL files you'll need to flip Y-Z planes to place details correct on printing table.
Use free for your needs! ;)
