_This is a sensor probe inspired by Bertho's work as well as other people's work, old patents and some original ideas._
_It is used to measure and digitize / scan objects by detecting when and where the probe touches the object._

_You will have to print 3 parts (could be made with a cnc mill or a lathe as well) and make 2 pcb plates. (could be done by hand if you are good at it)._
_It requires no soldering on the steel balls (it can be difficult)_

_This one is made to be used in a hobby CNC mill (43mm collet mount) but the concept can easily be adapted to any kind of CNC machine (3d printers, mounted in the spindle, measuring rig...)_
_The electrical contact is cut as soon as the probe touches something from any direction._

_Here is how it works:_
-The lower PCB hold the balls in place
-The upper PCB presses the balls and makes sure they go nowhe
