Parametric Coach

This is a parametric tramway, metro coach, or subway car depending on what you're looking for. You can modify its dimensions, number of doors and probably other things.

Its main feature is opening doors. It has sliding doors for the passengers and swivel doors for the driver and in the rear end of the coach. It is inspired by Kyoto tramway and St.Petersburg metro.

With the default dimensions it's roughly the same size as typical Tomy trains, but it's not really compatible with plarail or Brio/Ikea.

The easiest parameter to modify is ndoors. I only tried printing with 2, but but try 3 or 4 or 20 ;)
