      3D models take some time to learn to construct but its a skill you can
      learn which does not require access to expensive machinery and in fact
      the design side can be done with software that's either free software or
      zero cost proprietary software. It's also (at least this side of the
      pond) a skill that is now taught in schools as part of technical
      education - so kids are coming out of college having done 3D printing
      work, 3D CAD and the like.

      For non printable parts American Z is well served with trucks, wheels and
      couplers easily available.

      For things like weights or small parts that are too fragile when printed
      you can also do white metal drop casting at home without anything major
      (except maybe permission from the household authorities to use the
      kitchen as a metalworks ;) )

      There isn't a fundamental barrier to doing this stuff yourself, likewise
      CNC machining and tool making. You can get hand plastic moulding machines
      for peanuts second hand. Not something you'd want to run a major
      production run on but perfectly good for very low volume work, and much
      easier to cut tools for as you don't need ejector pins and other
      complexities.

      The key to bringing production back home wherever you are is to go do it.
