Our new tutorial is a walk-through dedicated to Blender users. It outlines the process of preparing your model for upload to the site, along with a brief introduction to the Sketchfab user interface and material editor.
There is also a dedicated Blender exporter here that allows users to quickly upload their models to the site.
You can find some final renders of this model on blenderartists.org.
If you feel like writing a tutorial to showcase how to get the most of Sketchfab with your favorite software, feel free to reach out at firstname.lastname@example.org!
