Can't find 'model-loader' extension from libgdx project

[T4d3o]

Hello.
I'm trying to follow this tutorial https://github.com/bitstars/droidar/wiki/Using-3D-model-files-in-DroidAR-%28like-.obj-or-.m3d%29

But I can't find the extension 'model-loader' of libgdx project. https://github.com/libgdx/libgdx/tree/master/extensions

Would it be possible for someone to share this extension?

Here is a previous version of the libgdx with the model-loader folder in the extensions:
https://github.com/libgdx/libgdx/releases/tag/0.9.8

@VictorPurMar is there any way we can update the wiki to make note of the exact version to use? Spent 2 days looking for this.
