A new hotend cover for two Noctua fans. (Noctua NF-A4x10 FLX 40mm)
The printer is not quiet yet - but it is much more tolerable now than with the standard hotend cover (and its noisy fans).
If you download or print this hotend cover: please give me a like! (it was a full weekend of work)
dB before: avg=50, peak=55
dB after: avg=45, peak=50
Not much, if you look at the values - anyway: before the noise was unbearable, now it is bearable.
BTW...for my K8200 it is: avg=38, peak=48 (fan@100%)
4x screw M3x20 (fan/front)
2x screw M3x6 (chassis/rear)
2x screw M3x10 (chassis/top)
8x nut M3
An improved version can be found here.
