I noticed that sometimes we could not access BlendSwap which said "It's likely the website's certificate is expired."

Like Google Poly 3D models, I created the page where you could download BlendSwap 3D models I used in my videos, just in case you couldn't access the site.

Click the corresponding link. Click the download mark button at the top right to download the model.

Poly was shut down on June 30, 2021. You can download all the Poly .obj models I used in my videos from here:
