I made this for simple enclosure cooling that can be used with dedicatetd hepa filters.
Propably it needs to be rebuild because of noise it makes but it can be just my fans that are very noisy.

EDIT: after testing it for some time I realised that blower for air intake will be better option. I will post here model when I end it. It will be suitable for 4010 blower. Also Iam making simple mount for 120x120 fan for backplate just to get some more air for mainboard cooling and to cool down stepper motors.

I recomend printing this in PETG or ABS because it seat near super hot stepper motor that propably will melt PLA.
