BIQU H2 4010 Fan Duct

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! 

Do note that this duct can be paired with my other side-mounted duct (also used with a 4010) for a very powerful airflow from two directions. The combo works quite well with my BIQU H2 mount. The carriage mount contains updated files for both ducts, so don't worry about using this page (in that case). 

• File updated to V2.3.1 - the extruder gear was rubbing against the print, as the hole I used to hollow out a space for the gear 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.  
• File updated to V2.4 - I realized that over time the heater wires are messing up and warping the duct with the way I have them wired (check pictures to see). I've made an update to the file so the wall is 1mm thicker(ish) and placed a small inset so the wires can go through without warping part of the print. Pictures added. Leaving V2.3.1 for anyone who likes the previous design better.
