A browser extension that allows you to export the scans made for the Invisalign teeth aligners to .obj files.
I am not affiliated in any way with Invisalign. I just created this because I wanted to 3D print my jaw as it was before using aligners.
The code is very sloppy but I'm sharing it in case someone finds it useful. Keep in mind I only had one input to test (my own jaw scan) so it may not work in other cases.
Load the unpacked extension in your browser. With the extension loaded, if you visit the Invisalign web viewer (with an URL share.invisalign.com/treatment-viewer/*) you can click in the extension to export the 3D model to a .obj file.
