gamedev44/Fabulous-Ripper — reverse-engineered prompt

I want a simple Chrome tool made as Tampermonkey user scripts that works on Sketchfab model pages. When a model page is fully loaded, it should show download buttons in the viewer so I can save the model and its textures to my computer. There should be a main button that shows up at the top right when possible, and a backup button at the top left if the main one does not appear.

Please make it easy for a normal person to install and use. Include clear steps for adding both scripts in Tampermonkey, turning them on, opening a Sketchfab model page, waiting until the viewer is fully loaded, and then clicking the button to download. If it helps, include the simple images or examples showing what fully loaded looks like and where the buttons appear.

Keep it straightforward and ready to use in Chrome. Look up current docs online if you need to.
