Wanhao i3 120mm Fan Mount PSU Control Box Back Plate

prusaprinters

<p>Korzar designed a very useful 120mm fan mount for the Wanhao Duplicator i3 control box, but unfortunately it is not very suitable for those of us with the older non-sloped front style control box (from V1 and some V2). Also there are a few areas that could do with some improvements.</p> <p>So I designed a new one based on the ideas of the original, with some useful features -</p> <ul> <li>Suitable for both old and new control boxes</li> <li>3 part design, TOP / BOTTOM / COVER, which makes printing easier</li> <li>Only one screw to undo if you need to open the control box</li> <li>The fan is fully covered in a honeycomb grille, which is much better aesthetically, and also allows fitting a dust filter</li> <li>Optimised wall thickness, makes printing easier and faster</li> <li>Minimal support required</li> <li>Cable bundle and AC socket on different sides, which makes cable management easier</li> </ul> <p>Note that by default the AC socket is on the left, cable bundle on the right. Mirror it in the slicer if you need them reversed.</p> <h3>Print Settings</h3> <p><strong>Notes:</strong></p> <p>No support needed for TOP and COVER parts.</p> <p>Support required for BOTTOM part.</p> <p>0.3mm layer height for optimal print speed. Finer layer height works too.</p> <p>1.2mm shell for optimal print speed, as the main walls are 2.4mm thick, so no infill is added there, hence much faster print time.</p> <p>Note that the bed surface contact area is small for TOP and BOTTOM parts, so use a brim if needed.</p> <h3>Post-Printing</h3> <ol> <li>Add an M3 nut to the TOP part. It will be a tight fit so use pliers to push it in if needed.</li> <li>Remove the original fan cover from the control box, and remove the AC socket from it.</li> <li>Put on the BOTTOM part to the control box, with three M3 screws that are at least 5mm long. Then put the AC socket onto the bottom part.</li> <li>Put on the TOP part to the control box, with three M3 screws that are at least 5mm long.</li> <li>Put a 120mm fan (and optionally a dust filter) onto the COVER part, with the self tapping screws that came with the fan.</li> <li>Plug in the fan connector, and put the cable bundle into the slot.</li> <li>Put the COVER part onto the control box, by clipping the bottom first, then use an M3 screw (at least 5mm long) to secure it.</li> </ol> <p>Done.</p> Category: 3D Printer Accessories
