That's what I'm doing (editing in openscad). I did see another thingiverse mention that the current upstream (beta/alpha) version of openscad can read the same parameters and present it. I'll do a test print of the default setup to see how my printer does - to understand limits of all the settings. Anyway - thanks for posting the scad file. It makes it really straight forward to use.
