While poking around on the web, wondering how I might one day get super accurate bed leveling or precise backlash measurements, I came across the concept of the "renishaw" touch probe and found one on thingiverse, but with no 3D printed parts, so I stole all the ideas, but turned it into a mostly 3D printable contraption:http://home.comcast.net/~tomhorsley/har … ishaw.html
Now all I have to do is work out some minor details, like a probe I can screw on the bottom and how to interface it with a 3D printer :-).
