@Printenna 3D Hubs offers a free widget to put on your website. They give you html code. Look in your hub dashboard. Let me know if you need more help.
Thanks.
I think the best way is using https://sketchfab.com/pattap
it is a free hosting and presentation 3D models on web browers.
That mean, you can embed the “video” code into you website , easily like youtube ebeding <3
Another way, what is your website sourcecode? Wordpress? SO there are some plugins that help you manage, show, and compute STL/OBJ specifications
At that time, on my website **Dịch vụ máy in 3D (**https://in3dplus.com). I have been using a “freesource” embeded , you can see at: https://in3dplus.com/xem-file-3d-stl/
Tell me, if you need one!
Do you have a link for the “freesource”?
