How it works

📁 STL files

3D viewer with orbit / pan / zoom. Dimensions, volume, surface area, triangle count.

📝 GCode files

Reads slicer-embedded metadata: print time, filament length / weight, layer count, temperatures, slicer name and version.

📦 3MF files

Shows the embedded slicer thumbnail plus the print profile, filament profile and machine settings.

🔒 Files never leave your browser

Everything happens client-side. No upload, no analytics on the content, no waiting.

🌏 Works with anything

Bambu Studio, OrcaSlicer, PrusaSlicer, Cura, SuperSlicer, Klipper macros — we read what your slicer wrote.

🛠 Made by a workshop

Built by the Hark Tech repair workshop. K2 and Bambu A1 owners, daily users, no marketing fluff.
