Is there a DIY Arduino or Raspberry Pi Coordinate Measuring Machine published in "Instructables"?

I wish to build a coordinate machine using x-y-z movements controlled by a microprocessor that can measure a scale model by touch of a probe or by reflection of a microwave.  The base machine would handle an envelope of 8" x 8" x 8" and use one or a combination of the best of the CNC laser cutters, 3D printers, etc.  Whether the microwave non-contact, crash avoidance, technology is sensitive enough would be interesting.  A couple of contact probe articles have been published and are the basis of commercial "Coordinate Measuring Machines" (CMM) and would be interesting if they are sensitive enough as a DIY project.  The end result would be to write a file with the x-y-z coordinates of say a model car, and knowing the scale of the model, one could multiply the data by the scale factor and have "Full Scale" coordinates of the cars' surface for building a kit car body.  A 1939 version of this project is on display at the CORD/AUBURN  Museum in Auburn, Indiana.  A 1939 Cord in 1:10 scale is shown as a clay model with half of the car finished.  The coordinate machine's purpose was to measure the right hand side completed in clay and produce a finished 1:10 scale model by finishing the left hand side symmetrically from data obtained from the opposite side. While interesting, it is a manual machine.  I am seeking an electronic, programmable, DIY version.

There are things like the DAVID scanner that can do that without touching

If you are asking for somebody to create such an instructable, I suggest you write a forum topic, as you will get more views there.
