Case for DC42 differential IR-Probe as Z-Probe

thingiverse

A monting case designed for David Crockers differential IR z-probe (Duet controller board) To mount the bottom case thorugh the PCB mounting holes, I drilled the PCB holes (carefully !) to 3.0 mm for M3 screws. The top cover (with included pin head lock) can easily pressed on the case and it snaps in. There are redundant notches included to allow removing and reattaching the cover to the case. Best filament would be a transparent one, but I added additional window hole into the cover for allowing the indication LED to shine onto the print bed for non transparent fialment. The tolerances used for this STL files are choosen to match the FFF process I use currently. Print Settings Printer: Mendel Max Rafts: No Supports: Yes Resolution: 0.15 mm Infill: 30 % Triangular Notes: I use Extrudr Green-Tec filament when developing this case : Print speed is 55 mm/s. 3 perimeters 0.27 mm extrusion width 0.4 mm nozzle Filament cooling at 100 % No surface optimization yet on print process Post-Printing remove support and stringing Needed to remove support structure and some stringing remains. This case was made tiny, therefore the PCB needs to be inserted diagonal. Some more optimization potential to reudce the case size, would be to remove the post notches.
