Extrude checks 3D-print files before they reach the printer
A free iPhone, Android, and browser viewer for inspecting 3D-print files, measuring models, and estimating print properties.
- For
- 3D-printing hobbyists checking models away from a computer
- Worth noticing
- Measurement taps snap to corners and edge midpoints; the app’s anonymous counters report 15,000+ models opened since September 2026.
Field notes
The app accepts files from Files, email, chat apps, Printables links, and ZIP archives; the browser viewer supports a narrower listed set and reports model size, volume, and triangle count. Print estimates use the user’s own settings, while sliced 3MF projects can display slicer-provided figures alongside them. The developer says features have often originated in user emails and credits contributors by name; the app’s counters are described as anonymous and omit IDs and file names.
