Case for DC42 differential IR-Probe as Z-Probe

thingiverse

A custom enclosure designed specifically for David Crocker's differential IR z-probe, which is integrated into the Duet controller board. To securely fasten the bottom case through the PCB mounting holes, I carefully drilled the holes on the PCB to 3.0 mm in diameter for M3 screws. The top cover, featuring an included pin head lock, easily clicks onto the case and snaps into place due to redundant notches that facilitate removal and reattachment of the cover. For optimal visibility, it's recommended to use transparent filament; however, I added a window hole to the cover to allow the indication LED to shine directly onto the print bed for non-transparent filaments. The tolerances used in these STL files are carefully chosen to match my current FFF process. Print Settings: Printer: Mendel Max Rafts: No Supports: Yes Resolution: 0.15 mm Infill: 30% Triangular Notes: I developed this case using Extrudr Green-Tec filament, which is characterized by its high quality and durability. Print settings include a speed of 55 mm/s, three perimeters, an extrusion width of 0.27 mm, and a nozzle diameter of 0.4 mm. The filament cooling system is set to 100% capacity, and surface optimization has not yet been implemented in the print process. Post-Printing: Removing Support and Stringing: After printing, it's essential to remove the support structure and some remaining stringing. Case Design Considerations: Due to the tiny size of this case, the PCB must be inserted diagonally. To optimize the case design further, consider removing the post notches to reduce its overall size. PCB Installation (Insert Diagonally): Mounted to the Printer: Case Closed: Remember to test your printer's functionality after assembly!
