CGDigest has a nice compilation of 45 free models gathered around the internet.
Bellow is a list of 45 3d models gathered from various sites. I have only included models that are useful for architectural visualization purposes (3d cars, bathroom items, furniture, electronics, urban elements, etc.).
Some good ones in here if you’re into architectural work, like the (Shown) Escalator model. Those things are a pain to do yourself (so I’m told).
Thanks for the information, very helpful for my works
