Creality Ender 3 fan duct
thingiverse
Puts a BLtouch sensor inside of the fan shroud for a stock Ender 3 or CR-10 to get it as close to the nozzle as possible. Part cooling duct designed to accept a Sunon 5020 GB1205PKV3-8AY Maglev blower fan for good air flow and quietness along with longevity. Duct blocks heatsink fan from blowing on part for non-pla materials. I print it in PETG with supports for the fan mount only on a glass bed on one of my heavily updated Ender 3. I included a printable drill guide that slips over the stock fan shroud for drilling mounting holes for the Bltouch. Started out as a duct I found on Thingiverse but its been so heavily modified I'm not sure any of the original is left. Will have to modify firmware to run fan since its only 12v. I limited my max fan speed to 128 instead of 255 since this equates to 12v.
