To silence the fan even more, print my Snap-On 5015 Blower Silencer

Design:

I have created this model with the following considerations:

- efficiently guide air to the back of the baseplate and into hotend - ultra-lightweight - much stiffer probe mount - better clearance to extruder lever - snap-on mount for the 5015 blower - reuse original screws only Printing instructions:

- you need to print BOTH MODELS backplate + 5015 mount - printing orientation on bed as shown in picture - material: use PETG or better (avoid PLA, due to low heat resistance) - layer height: 0.2mm or smaller - use 5 perimeters - supports on build plate only - infill: any Fitting instructions:

- disassemble the extruder and replace the backplate using original screws - use 24 Volt 5015 blower and splice/solder/crimp onto a stock connector - file down small amount of plastic on the bottom part of the blower → this will ensure a tight fit in part - snap-on the blower and rotate it in it's final position - secure the fan with a glue gun - don't forget to do a PID calibration for your extruder !!! _________
