Reinforced cooling fan duct for ender 2

thingiverse

This is an updated version of Timah81's "Cr10 40mm cooling duct with beefed up mount". https://www.thingiverse.com/thing:2350437 Because I also installed jneilliii's "Radial Fan Fang for Creality CR-10" on my Ender 2, I discovered that mounting all the gear to the x-carriage only with the two M3 screws holding the hotend was a bit flimsy and wiggly. So I added an ear with two holes, allowing the entire assembly to be secured also to the left side using the stock extruder housing screws in the carriage threads. You will need 2x M3x20mm screws to mount the part together with the hotend to the carriage, which are the two golden screws visible in the picture where the allen key for the 2 supporting screws is shown. As the upper right screw is a bit hard to reach with the allen key, there's a small hole in the front of the fan frame to stick the tool through (see picture with allen key). The pictures now show the final part. The 4 vertical holes on the left ensure airflow to that side as the space behind the mounting screw is filled by the supporting ear. The right side has clearance to the carriage just like before. For the dimensions and hole positions, I used Ross_K's "Creality Ender / CR10 X-Carriage assembly" which is very helpful for designs around the hot end - thank you! (The fan guard and LED-holder in the picture with the completed assembly are a custom thing I designed for some old LED-strip I had laying around... connected it in parallel to the Hotend-Fan)
