The PGFUN DIY CNC Touch Probe has a toolsetter mod kit that turns the probe upside down and provides a nice 10mm surface for measuring tools. I had issues with reliability on the Long John toolsetter and this probe solved them all. It's also shorter than the Long John and has cool lights!

The mod has a magnet but that doesn't work with the aluminum fixture plates on a Milo v1.5. This simple mount lets you friction-fit the base and has 20mm-on-center M5 bolt holes for securing it to the fixture plate using M5x12 BHCS that are part of the LDO kit/Milo BOM. A hole was left under the mount to make it easy to pop out the probe if needed (especially if glued). An M6 variant is provided if using a fixture plate with M6 threaded holes (such as the SMW Universal Fixture Plate).
