Import JSON, 3MF, and STL files

Bring in slicer settings from JSON and 3MF files, or inspect an STL as a model preview. When a file does not actually contain print settings, the importer now says so clearly instead of guessing.

Attach favorite filament

Optional, but useful. If this import belongs to one of your common spools, attach it now so the saved profile is more grounded and easier to find later.

No favorite filaments yet. Save a few common spools in Favorites and they will show up here.

Import Preview

Choose a file on the left and this page will preview the settings or model details we can extract safely in the browser.
