Saving an image of embedded sketchfab model on webpage

I have created a web page that embeddeds a sketchfab model and gives visitors on the page options to change various elements on the model. Once the user finishes their selections I need a way to be able to save a pdf (or image) of the changes. I have looks at several screenshot apis and tried using html2canvas but nothing has worked. Is there code or api I can use to do this?
My model is here: Sueños 53. I also have set it up so you can share your changes for example using this link Sueños 53

Any help would be greatly appreciated.

Thank you,


Did you try getScreenShot ?
A sample here
