Prusa i3 MK2S Fan supply fan duct 80mm

I made an enclosure for my MK2S using a modified Ikea Lack table.
As I did not want to remove the powersupply and mount it under the table, it needs some fresh air inside the enclosure.
I drilled
- 1x 75mm hole A right next to the PS
- 1x 75mm hole B on the opposite side at the top
and mounted
- 1x 80mm fan attached at inside on hole B that blows heat and fumes outside
- 1x dust filter attached at outside of hole A that filters air
- 1x this duct fan that directs all the cool air directl
