I use a ton of 3D Files as I love 3D printing in my spare time and I usually exchange them over Gmail and store them in Google Drive etc.. Google does not have a 3D Preview of files so I've built a small Google Workspace Addon that opens the file into a clean "Google like" web app that supports most files.

Would love to have feedback! Each file is treated purely in the browser for maximum privacy

What it does: * Generates parametric 3D models from natural language descriptions, with support for both text prompts and image references * Outputs OpenSCAD code with automatically extracted parameters that surface as interactive sliders for instant dimension…
