I tried to keep the design as universal as possible, so many more makers from the community can benefit from the progress of this project. I am in the process of creating a modular full gantry/hot end assembly including this UNIVERSAL PRECISION PIEZO PCB HOLDER for my reach3D printer. Check out this great crowdfounded open build from Nate Rogers: http://www.reach3dprinters.com/ It was designed to 3d-print, laser engrave, laser cut, plot, cnc-mill, plot tbc...great little machine, so precision Piezo is the ultimate way of attaching up to three high accuracy probing sensors.
The Precision Piezo CONTROL UNIT PCB in it's current revision (V1.22) will slide right on top of this holding attchment and fit snug. It has a zip-tie slot to keep it in place and safe. Attach it with 2.8x12mm tapping screws. The current hole distance is at 46.5 mm but feel free to modify to your needs of part placement.
