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. Other solutions existed but they were full of ads and looking absolutely terrible. It got a bit of traction (around 400 users) on the store so thought I would share it here! Would love to have feedback! Each file is treated purely in the browser for maximum privacy

A technical breakdown of a single frame can be found here: https://ktstephano.github.io/rendering/stratusgfx/frame_anal...
