4020 blower to 30mm fan mount adapter

thingiverse

I've come to realize that my small 30mm fan isn't cooling my E3D V6 hot end sufficiently. I created this adapter, which enables me to mount a 4020 blower to a 30mm fan mount. It aligns perfectly at the top and fits snugly under my effector but does protrude quite far in the back, so be cautious with larger prints. During my bed leveling routine, the rear of the blower is pressed against the black timing belts on my Z tower, barely making contact. These LED strips are truly fantastic. The adhesive proved too weak, so I used super glue to attach them to the bottom of the 4020 blower. I wired them in parallel with the blower. My printer is set to automatically turn on the hot end fan at 50 degrees, and it's perfect – the LEDs light up as well. I employed (1) 3X20mm socket head screw and (1) 3mm nut to secure the blower to the mount. I used (2) #4 sheet metal screws, 1/2" long, to attach the adapter to my fan shroud securely.
