D.boe's Qidi X-Max Extruder Fan Upgrade (no extra parts needed!)

(Check out the new 40mm version, here: https://www.thingiverse.com/thing:5222934) I must admit, I LOVE my Qidi X-Max... However, when I first got it and took it apart, there was a glaring design flaw that is also well documented on the web. NO AIR GETS TO THE LOWER HEATSINK (closest to heatblock) to prevent heat creep. So I did something about it, without having to buy additional fans, screws, etc. Instructions: 1- remove carriage lid 2- remove extruder from carriage (both fan ducts fit both extruders) 3- remove extruder fan, discard small white spacers. 4- replace spacers with either D.boe duct of your choosing. (I recommend using the one with the lower duct as it keeps air on the heat fins and off the actual heat block) 5- Use a Dremel or other device to remove the top edge of the carriage plastic just under the extruder fan... this allows the device to work--- by redirecting some cooling to where you need it most!!! 6- reinstall fan on top of new duct using stock screws. 7- Enjoy happy printing with much less heat creep induced PETG clogs. I printed without support.... No issues. NylonX
