Just in case anyone is still playing this I am still putting up the occasional new model on my github:
https://github.com/PhoenixRiver/bricksperience-models
I'm a little irregular with when I have time and quite a few of the models are quite simple - though there are some of the more complex models for those who like a challenge, usually architecture type ones - I have put consideration into them such that even with few or no upgrades they should be doable... the usual problem is roofs or flying vehicles (which I tend to put in the air for aesthetic reasons, but also sometimes for build reasons as their undersides can be difficult if they are on the ground).
All said though I've built up quite a little collection, so feel free to enjoy them :)
PS For the Bricksperience VR players: I'm afraid that due to space constraints on Github I've not included the screenshots of the models - if you would like them you can generate them using the editor in the non-VR version of Bricksperience by loading the model file and then saving them and checking the screenshots box at the upper left.
