3D printing businesses need a way to quote customers accurately without manual calculations. This app embeds a quote calculator directly on your storefront. Customers upload STL or 3MF files, view their model in an interactive 3D preview, and see pricing calculated automatically from volume, material density, and infill settings. Prices are displayed in the customer's local currency using live exchange rates. The quoted price is added to cart with one click, ready for standard Shopify checkout.
