Printerials is my own product, in development since December 2024 and live at printerials.com since late August 2026. The catalog holds filament and resin lines with colors and pack sizes, printers and upgrade kits, built from open data with the source credited for every figure. A crawler of my own checks prices at web shops daily and keeps the price history, with shipping costs and VAT per country. Around the catalog sits a personal workshop: your spools and printers, what you use and alerts for price, stock and drying. A Spoolman-compatible API connects it to Klipper, OctoPrint and Home Assistant. Technically it is a Next.js application with Prisma on MariaDB and the crawler in a container of its own, all on Coolify. A React Native app is in development, as is an open-hardware scale on an ESP32 that weighs leftover filament and reads NFC tags.
