Done in Moray for Windows 3.5 and exported via my scad export plugin. This uses http://www.thingiverse.com/thing:3575/#files (parametric involute gears V5 by GregFrost).
The general design has been tested in 2/3 (or perhaps 1/2) scale with PLA and a 0.2 mm nozzle, and worked well. Currently printing full-size version after modifying some proportions (thicker frame for strength, thinner gears to make pens work better). Expecting 5-10 print hours at 40 mm feedrate, 0.2 mm nozzle and 0.15 mm la
