Where to learn Industrial design Model Making?

I would look towards the online workshops for model railroading hobbyists.

You may or may not be doing a model railroad project, but they cover everything in your list and in your list of topics.

@Jonathan_hodgkins Look into this guy in Cincinnati Ohio Joshua Haldeman

@Yellowdog, are you a model railroading hobbyist yourself?

I was—until I was 35 and moved to Alabama. I really didn’t do much after I left my parents’ home when I was about thirty. And I never was able to get back to it because of economics and loss of the use of my right hand in 2011. I continued to answer questions on Model Railroading Q&A websites.

There is one model railroading organization that I occasionally get advertisements for that had a $1 for the first year offer. There were online workshops that cover everything including everything those which @Jonathan_hodgkins mentions above—except for 3-D printing.

There are DIGITAL model buildings available for online games that people offer / submit / sell, and I have often wondered how difficult it would be, if difficult at all, to feed this info into a 3-D printer and make models.
