Hi, where should the button appear? I tried to use the script bu i couldn't see it.

I had to change
// @include /^https?://(www\.)?sketchfab\.com/.*
to
// @match https://sketchfab.com/*
to make it work on Violentmonkey, but then it works like a charm!
It just breaks the viewer on the page, but that's a minor inconvenience since it allows the download of the models.
