Haha- I can relate, but from the other side of it. It would probably take me an hour or less to draw the rack and pinion I needed in CAD, but I figured there had to be a customizable setup on Thingiverse. Found the original http://www.thingiverse.com/thing:5505 , and then spent the whole day hacking in openscad (never used it before)! But next time I need a rack and pinion (or to tweak my current project) it'll be smooth sailing...
