I have several ring designs, each parameterized for size and rendered at every quarter US size from 1.5 to 13. I wrote some nodeJS scripts to upload all the models to Shapeways in bulk through the API. But creating a Product with all 46 possible sizes, available in multiple materials is UNBELIEVABLY tedious, because the only way to associate the appropriate model with the size-material variant is by-hand in the web app (as far as I can tell). And the web-app is grindingly slow to use when there are a lot of models in the drop-down. _Please_ create an API endpoint for products and variants. If the API also allowed getting/setting the price for each variant, that would be also much appreciated, although the CSV wizard is a plausible work-around.
