make_part — Make a custom part
Build, check and price a custom 3D-printed part from exact sizes (mm): plate with holes, L-bracket, spacer/standoff, washer, or box with lid. Shows the part in 3D with its price and an Order button. Sizes left out use sensible defaults. Use again with new sizes or options when the customer asks for changes.

}price_file — Price a 3D file
Price the customer's 3D file (STL, 3MF, STEP or OBJ) and show it in ply's card. Without a file, shows the card with an upload button (with sourceUrl: the model page to download it from). In ChatGPT, pass a file the customer attached. Pass `path` (from an earlier result) to change options for a file already priced.
