[Guide] Ripping models from Sketchfab

Hi guys there is a tool to rip models very quickly from Sketchfab but it doesn't work anymore, unless change some of the code. These are the tools: https://github.com/tianve/sketchfab - https://github.com/1337ad/sketchrip

Just need to replace regexp detection part with the following code. NOTE: I don't know which one the code works with.

var jstext = req.responseText;
if (jstext.indexOf("drawGeometry:function(e){") >= 0) {
jstext = jstext.split("drawGeometry:function(e){").join("drawGeometry:function(e){window.drawhook(e);");
}

What is regexp detection part? Anyone able to make it work?
