Titan X-carriage with piezo Z-probe

A remix of DJDemonD's titan + piezo mount, to fit onto an open-build mini-gantry. To give a firm enough mounting it uses 3 holes. I added a groove and hole to pass the piezo connector out of, plus a stud to screw the Precision Piezo PCB onto. Like the original, a decent dab of superglue front & back is enough to hold the piezo and force it to flex with the mount. Works great - cut my probes typical SD-from-mean in half and almost eliminated vibration artefacts, both because the nozzle is now so
