Mosquito Style Hotend Mount for Prusa Mini

prusaprinters

<p>A drop-in replacement mount for "Mosquito style" hotends (original and clone) using the bowden (v6/BMG mount) adapter.</p> <p>Designed from scratch with the goal of a mechanical stable and reliable mount solution. The fan shroud has been integrated into the adapter.</p> <p><strong>Position Offsets</strong></p> <p>Compared to the stock hotend, the nozzle is moved <code>-4mm</code> in Y direction and <code>0mm</code> in X direction - this requires a one-time modification of the startcode in cura/slicr to avoid the initial prime line printed outside the plate.</p> <ul> <li>Don't forget to re-calibrate the first layer and setting z-offset to 0 for calibration!</li> <li>Dont' forget to change the PINDA/MINDA position!</li> </ul> <p><strong>gcode</strong> - replace the first G1 line (with Y-2) with the following</p> <pre><code>G1 Y1 X179 F2400 </code></pre> <p>Additionally, set the Extruder1 "Y Nozzle Offset" to <code>-5mm</code></p> <p><strong>Additional parts</strong></p> <ul> <li>2x screw <code>M3x20</code> (left clamp and bottom x-carriage)</li> <li>2x screw <code>M3x25</code> (bottom fan and top x-carriage) </li> <li>1x screw <code>M3x35</code> (top fan)</li> <li>5x hex-nuts <code>M3</code> (mount adapter)</li> <li>1x self-locking hex-nut <code>M3</code> (top fan screw)</li> </ul> <p><strong>Recommended Modifications/Tweeks)</strong></p> <p>The stock heater-cartridge and hotend-sensor cables are about 5cm too short to be fixed with the PINDA clamp. But you can run the cables outside of the main cable strain (see photos) - the recommended solution is to use longer cables.</p> <p>Theoretically the hotend could be mount inverted (hotend block directly under the fan) but i would <strong>avoid</strong> this because the distance in between is too short and the plastic may melt!</p> <p><strong>Tests</strong></p> <p>As of now, i've only tested the adapter with a clone and not the genuine mosquito. The clones have a much higher heat dissipation but the cooling is still working great (you can touch the whole metal frame with your fingers).</p> <h3>Print instructions</h3><p>For optimal results, use your custom printer settings with the <code>stl</code> file!</p> <p><strong>Used print settings (gcode+photos)</strong></p> <ul> <li>Layer height: <code>0.20mm</code></li> <li>Adapter-Orientation: regular</li> <li>Clamp-Orientation: rotated at 180deg for best dimensional accuracy</li> <li>Material: BASF Ultrafuse PET (transparent)</li> <li>Supports: Adapter(yes, @80deg), Clamp(no)</li> </ul> <p><strong>Suggested print settings</strong></p> <ul> <li>Layer height: <code>0.10-0.20mm</code></li> <li>Material: PLA/ABS/ASA/PET/PETG</li> <li>Supports: Adapter(yes), Clamp(no)</li> </ul> <p><strong>NOTES</strong></p> <p>The dimensional accuracy is critical for the snap-fits. Depending on your material, scaling might be necessary! (use negative horizontal expansion in case the clamp or screws are not fitting)</p>
