It has been a while since the last post in this forum, but there is still new stuff out there that wants to be shared.
I stumbled upon a whole bunch of 3D Models from dmaland: https://dmaland.deviantart.com/gallery/692466/3D-Meshes-and-Data
There is a little bit of everything: Space Ships, Interiors, Parts, Space Objects, etc.
The models are CC-BY and you can even patreon the artist
. He seems to be currently active, so help him out if you like what he is doing.
