I dig Sketchfab. It's a great simple tool for showcasing anything 3D.

You upload a file, you get an embed code or a link, and you pop it on your website.

Now you can show users something in 3D.

The free plan is generous - the way they meter out the cost is a little strange to me - you get 10 file uploads for free each month.

Usually, tools like this charge via views of your embeds, but I much MUCH prefer how Sketchfab does it.

That way, as long as something is uploaded, you don't have to worry about anything else going wrong.

I've used this to show clients 3D files I've designed for them, and more.

I plan to use it for some niche 3D stuff in the future, but it's generally considered, from what I can tell, the de-facto 3D viewing tool on the internet.

If you need to show off something 3D anywhere, Sketchfab is a good option. :)
