Really a great build....

Well, I can't take credit for the design since it's semi-accurate to the original. I don't envy the crazy people who have Stollies now, though. Keeping my Fiero running is nothing in comparison!

Anyway, as for leadscrews, what are you using to draw, or at the least, are you hip to / have you played with OpenSCAD?

I have a pretty good library for gears I got off github or someplace, the joy of opensource means you don't have to write it yourself. I also had an interest in leadscrews, was looking at doing my own actuator-linear movement thing, but the geometry made my head spin. I did find a library or two where it's been done and didn't get any farther, but can scrounge up the links if they'd be useful.
