Never heard of pythonscad before, but I've always thought it would be a good idea (if only I honestly had the skill to make this myself). Thanks for the links!
It was absolutely game-changing for me --- I'd been flailing at this for a long while, and was most of the way there w/ RapSCAD, but stuck on it not being very popular --- within a week of release I had a working version of my library --- it's been nothing but upside since then.
