This Fusion 360 file will parametrically create gears that can work with threaded rods or bolts either as a worm gear or as a pinion (using the threaded rod as a rack).
The thread is defined by its dimensions as parameters and a diagram is included to explain what those are. You can either look the values up for a particular thread, or create a thread and measure it in Fusion 360.
Clearance parameters are also included for fine tuning the fit.
This is marked as a work in progress for two reasons:
I couldn't get the final Join operation to work parametrically (would break if I changed the number of gear teeth) so you'll have to perform that operation manually. If anyone knows how to do a "select all" for bodies or some other workaround, LMK!
I've only tested-printed a single size: 1/2-13 60 tooth. It worked fine, but it's a sample size of only one.
