Many years ago I purchased a used set of plastic parts for a Sell's Mendel (they actually came from Prusa!). I self-sourced most of the remaining parts and put it together. It works to this day (with minor repairs). :D
I did not make the train. I did not make the train tracks. I didn't even make the whistle. I did put these things together, and people seem to really like it.
