BIQU H2 4010 Fan Duct

prusaprinters

<p>This design is a simple fan duct made for the BIQU H2. It mounts on the front of the extruder itself and is very simple. The duct is fixed position, as this is just easiest for me to design - please feel free to comment if you have any issues, and I'll be happy to help out!&nbsp;</p><p>As of November 2022, this design is still a work in progress. Version numbers are included with the files when uploaded. As a note, the design is plenty usable, I'm just too perfectionist to stop once it only works. :) I'll be making modifications within the next 2 weeks and the final design will be done soon.&nbsp;</p><ul><li>file updated to V2.3 - the extruder gear was rubbing against the fan itself so I have added a bit more to the thickness of the wall for mounting.&nbsp;</li><li>update V2.3.1 - the extruder gear was in fact rubbing against the print, as the hole I used to hollow out a space for the gear (in Tinkercad) was not correctly aligned. The error has been fixed, and I've now added to the version number another decimal, signifying a minor change to V2.3. &nbsp;</li></ul><p>&nbsp;</p><p>Do note that this duct can be paired with my other <a href="https://www.printables.com/model/316890-biqu-h2-4010-fan-duct-side-mount">side-mounted duct </a>(also used with a 4010) for a very powerful airflow from two directions. The combo works quite well with my <a href="https://www.printables.com/model/271680">BIQU H2 mount. </a>The carriage mount contains updated files for both ducts, so don't worry about using this page (in that case).&nbsp;</p>
