I myself made models from 1983 to 2014.
Thousands of models in each scale and execution made.
Possibly with lights or moving parts.
You can see products under 'model building / old site.
I also have done several years Courses / workshops for Technasium in the Netherlands.
Here teachers could see how they could make simple models.
Or in the old business model builders and novice trainees learned the trade.
It is therefore not difficult to understand why I made this course.
