M Prime One - Adjustable Hotend and Probe Holder

The M Prime One hotend and probe holder is designed for a LJ12A3-4-Z/BY probe with 12mm diameter. Since I already have a LJ18A3-8-Z/BX with 18mm diameter have remixed the original design.

If you have a sensor with a different diameter - no problem! Since the FreeCAD source file is included in the download you can easily change the diameter according to your sensor.

1. Open the FCStd-file in FreeCAD
2. Open the "Part" workbench
3. Locate the cylinder named "Change radius to fit your probe
