3D Print Pricing Calculator
3D Print Pricing Calculator is a WordPress plugin that lets customers upload STL files directly on a website and get an instant, accurate 3D printing quote. All file processing, volume calculation and pricing logic run locally on the server, with no external API or API key required.

The plugin parses the uploaded STL geometry to calculate model volume, weight, surface area and estimated print time, then applies configurable pricing rules based on material, print quality, infill percentage and color. Store owners manage pricing, currency and email notifications from a dedicated admin panel and track every uploaded file in a built-in file manager.
