In case you have an iPhone and you like to seem them in true 3D AR in your very own environment, I just have a tip and ask for feedback.
Aryzon recently updated their AR 3D Model Viewer app to support the SketchFab gITF format. The app, currently only for iOS, allows you to import your own content to view either in 2D AR (like Pokemon Go) or in true 3D AR if you have the Aryzon AR Headset.

Please, if you have any feature requests or would like to know more, let me know!
