The 3D Slash exporter lets you publish 3D files straight from 3D Slash to Sketchfab.
As of 3D Slash Beta 0.9.1, the Sketchfab exporter is natively integrated! As long as you have the latest version, you can already publish your models directly from 3D Slash.
You will be redirected to the model page. When processing is complete, you can view your model on Sketchfab, adjust rendering settings, and save the default view.
