Has anyone tried this 3D printed micropipette?

I was cursing Thingaverse and found a micropipette for the printing. Has anyone tried it? Does anyone have some ideas for calibrating it?

No clue, but this one looks better

True that, Koeng.

I'll print that one out and report back. Hopefully in the next week and a half.

There's this other one: http://www.thingiverse.com/thing:64977
But is less "professional" than the one you found.

To calibrate (and to find its precision) I would just pipette some water and measure its weight (avoiding evaporation). Then the "real" volume pipetted could be found by the density.
