Probe for surface scanning - CNC machine

cults3d

It took me several attempts to finally land on this design. To bring it into being, you will clearly need a 3D printer and some hardware components; specifically, an end stop switch, an LM8UU bearing, an 8mm spring, and a 6mm bolt with a minimum length of 40mm. I initially considered using an 8mm steel rod for the main part that passes through the bearing but ultimately decided to use a 3D printed component instead. After doing some rough math, I estimate that this probe tool cost me around two dollars - at most three if I factor in the two failed design prints of the probe tool. One of the standout features of this design is its ability to perform probing on uneven surfaces, which enables CNC jobs such as cutting or carving to follow the contours of the workpiece. In contrast, other probing tools rely on having electric conductive surface tape (like aluminum) applied to the workpiece - a requirement that isn't necessary with this probe tool since it uses a switch instead.
