<p>Reclaim lost build volume on your ender 3 with the thinnest mount out there! This mount is only 5mm thick while still being rigid enough to handle relatively fast accelerations without too much wobble.&nbsp;<br>The removeable fan mount makes the already hard to service H2 just a little bit easier and allows you to have two colours to match your aesthetic.&nbsp;<br><br>This model is designed specifically to work with Predy's <a href="https://www.printables.com/model/146957-mad-modular-air-duct-for-biqu-h2">“MAD - Modular Air Duct for BIQU H2”</a>&nbsp;</p><h3><strong>Print Setting Recommendations</strong></h3><p>The file "H2 MountPlate" makes use of sacrificial bridges to avoid support.</p><ul><li>0.15mm Layer Height (<strong>A must for the sacrificial bridges to work!</strong>)</li><li>No Support</li><li>100% infill for rigidity&nbsp;</li><li>I used PLA as it is quite rigid, however, ASA or nylon may be better choices.</li></ul><h3><strong>Hardware</strong></h3><ul><li>4x 6-8mm M3 Button Head Screws (6 and 8mm both work fine)</li><li>2x 20mm M3 Button Head Screws</li></ul><h3><strong>Assembly Steps</strong></h3><p>Using a screwdriver or similar, break through the sacrificial bridges on the rear of the mount. &nbsp;</p><figure class="image image-style-align-center image_resized" style="width:29.92%;"><img src="https://media.printables.com/media/prints/317177/rich_content/ed428fae-3937-42ec-9607-fc439a21a4cb/img20221114231010.jpg#%7B%22uuid%22%3A%22a429056a-5adc-42ce-ad71-a3e47f463d4e%22%2C%22w%22%3A3456%2C%22h%22%3A4608%7D"></figure><p>Tightly fasten the mount plate to the H2 with the first two 6mm M3 screws.

Using a hot knife I cut a slot to let the duct assembly clear the tensioner mechanism. It ain't pretty but it works<img class="image_resized" style="width:100%;" src="https://media.printables.com/media/prints/317177/rich_content/9729df3a-797d-403e-a1ef-0234ff796684/img20221114231212.jpg#%7B%22uuid%22%3A%22edbf59b0-dd70-462e-8258-f21aca24cd49%22%2C%22w%22%3A4608%2C%22h%22%3A3456%7D"></p>
