This isn't an aesthetic mod, it actually increases the K1's rear fan air pressure, and also, reduces the noise.

If you have an air filter in your Creality K1, you may have noticed that the rear fan doesn't have much static pressure to push the air through the filter.
A simple solution to this problem would be to replace the original fan with a stronger one.
But if you want a solution using the original fan, then this model will help you.
The proposal is to use two combined solutions: a Velocity Stack with an In-line Pressure Booster.
- Velocity Stack: It redirects the air to the fan inlet using the principle of laminar flow, creating conditions for the air to enter in a constant and orderly manner. This increases the flow, reduces turbulence, and, due to the lower turbulence, also reduces noise.
- In-line Pressure Booster: The air passing through the fan is accelerated and exits in a spiral flow (vortex). The booster corrects the flow direction, adding more kinetic energy in a single direction, giving the air more force to overcome any resistance. This is the same principle used in jet engines.
Bill of Material (BOM):
- 4 x Screw M3 x 8mm
To attach the booster to the chassis, use the M3x8mm screws.
To attach the Velocity Stack and the fan, use the original screws.
PS:
Don't fits on K1 Max, because of different fan size.
Fits on K1C, but nose of Velocity Stack hits on the bed. Maybe I make a new model fixing that
