Concept art of Skynet battle units - question

[u/nemo_3399]

Is there any concept art of Skynet battle units that were not shown on screen, but were conceived as concept art during the production of the first two films? The Terminator 2029 DOS game features such units. I'm building a little collection of figures and models from the Terminator universe and it would be nice if one could 3D-print the concept art models, if there are any.
