Siemens Controller
This model was produced for use as a hand-held prop at an event. Although we are usually only given a few drawings on paper, a photo, or a description of what is needed, we were provided very few details, in this case. As long the purpose and focus of the model is clear, and the intricacies of its components are not excessively numerous, we can turn out a product model like this in very short order and with minimal information.
