Hydra Fan Cover

<h3> Hydra Fan Cover for dual 5015 blower fans</h3> <h3>Concerns:</h3> <p>Airflow restriction is not a problem, I have run my printer for days without no heat creep issues. The many holes gives it good air throughput while hiding the internals from direct sight.</p> <h3>Why make your own?</h3> <p>I wanted a cover for the Hydra Fan Duct that:</p> <ol> <li>(Partially) Hides the internal wiring and Noctua fan color.</li> <li>Protects the fan</li> <li>Fitting together with<br/> a. 40x10 fan and a front mounted BLTouch.<br/> b. 40x20 fan.</li> <li>Fits - no matter the height of the blower fans, since they can be mounted in different heights depending on the nozzle/blower angle.</li> <li>Making my machine look just a bit more stylish while showing off the name of the totally awesome fan duct. :-) ### Hardware</li> </ol> <ul> <li><p>(Optional) Bracket used for BLTouch: <a href="https://www.thingiverse.com/thing:4617163">https://www.thingiverse.com/thing:4617163</a></p> <ul> <li>The bracket uses 4 screws which is perfect with a Noctua fan, since it has extra height on the corners due to rubber added.</li> </ul> </li> <li><p>2 M4 screws (approximately 30 to 40 mm long).</p> <ul> <li>Alternatively use 2 M3 screws (same length) and insert M3 brass inserts.</li> </ul> <p>### Printing notes</p> <p>No supports are needed, as the supports are build in.<br/> The supports are meant to be cut away with a knife or scalpel after print, see the Post-Printing section below for more details on what to remove.</p> <p>### Assembly notes</p> <p>This is tested and can be used with either:</p> <ol> <li><p>A 40mm fan 10mm deep and a front mounted BLTouch.</p> <ul> <li>To enable usage with a BLTouch you have to snip off the bottom cells of the grid as needed. See Post-Printing images below for example on how I made space for it.</li> </ul> </li> <li><p>A 40mm fan 20mm deep. The spacer is to put between the 5015 fans and the cover, if your spacing is larger/smaller just scale the spacer on the Z axis to match your setup.</p> </li> </ol> <p>The hole for the mounting screw is designed to be 4mm in diameter, but if yours end up being smaller than that use a drill to make it the wanted size.<br/> Personally I drilled the hole a bit larger and inserted 2 M3 brass inserts for the screws.</p> <p>### Change Notes</p> <p>Change notes will be updated as new features/changes are made.</p> <p>2020-10-20: Released</p> <h3>Print Settings</h3> </li> </ul> <p><strong>Printer Brand:</strong></p> <p>Creality</p> <p class="detail-setting printer"><strong>Printer: </strong> <div><p>Ender 3 Pro</p></div>**Rafts:** No <p class="detail-setting supports"><strong>Supports: </strong> <div><p>No</p></div>**Resolution:** 0.2 <p class="detail-setting infill"><strong>Infill: </strong> <div><p>20</p></div> **Filament:** [ Spectrum PLA Pro ](http://www.amazon.com/s?url=search-alias&amp;field-keywords=Spectrum+PLA+Pro&amp;tag=thingiverse09-20) Black Post-Printing ============= **Remove supports at the marked locations** <div><p>Remove supports at the marked locations.<br/> The top of the model (printing orientation) has a bridging layer which is expected to be removed to allow airflow.
