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!
