M Prime One - Adjustable Hotend and Probe Holder
thingiverse
The M Prime One hotend and probe holder is designed for a LJ12A3-4-Z/BY probe with a diameter of 12mm. Since I already have a LJ18A3-8-Z/BX with an 18mm diameter, I've remixed the original design. If you have a sensor with a different diameter, no problem! The FreeCAD source file is included in the download, so you can easily change the diameter to fit your sensor. To do this, open the FCStd-file in FreeCAD and then switch to the "Part" workbench. Locate the cylinder named "Change radius to fit your probe" in the Combo-view and change the "radius" value. If desired, click "File" -> "Save" to save your new value. Next, click on "Hotend + probe holder" in the Combo-view to highlight the holder and then click "File" -> "Export". Enter a name and select "STL Mesh" as the file extension/type. Save the file. Now you're ready for print settings. Printer: TEVO Tarantula Prusa i3. Rafts: No. Supports: Yes. Resolution: 0.4mm nozzle, 0.2mm layer height. Infill: 45%
