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.
