The exact DrMaker3D instant-quote price for printing a person's 3D model file, from the same engine and the same measurements as the instant quote page. Pass the file the person attached (as file), or upload it first: POST https://drmaker3d.com/api/upload as multipart/form-data with fields file (STL, OBJ, 3MF, GLB, glTF or PLY, up to 25 MB) and kind=printiq, and pass the "key" it returns as file_key. The file is kept privately by the studio for the quote. Returns the price, size, turnaround and a checkout_item to pass to create_checkout. Painted multicolor files, STEP files, parts too big for one piece and model links (Printables, Thingiverse, MakerWorld) are quoted by hand: it says so, and request_quote sends them to Rich.
