Description
On the original Creality K1 and K1 Max, the stock 6015 MCU cooling fan is mounted on four posts beneath the printer’s bottom plate. This leaves the fan sitting approximately 4 mm above the intake holes, allowing it to draw air from inside the printer as well as from the intended external intake.
This simple spacer/seal plate addresses that issue by:
Sealing the fan directly to the intake holes
Eliminating the ~4 mm gap between the fan and the bottom plate
Ensuring all intake air is drawn from outside the printer, not from inside the enclosure
On my printer, this resulted in a noticeable ~5 °C reduction in MCU temperature.
This model is designed for the original K1 / K1 Max.
Later revisions (such as the K1 SE) appear to have changes in this area, and the gap this part addresses may already be reduced or eliminated.
Before printing, it’s recommended to:
Remove the bottom plate
Measure the gap between the MCU fan and the intake plate
If there is little or no gap, this part may not be required. Advanced users may scale the height in the slicer if desired.
No supports required
PLA is fine; I printed in PETG
Any material you’re comfortable printing will work
This area does not experience high temperatures
Remove the bottom plate (6 screws)
Remove the MCU fan screws (4 screws)
Place the seal plate onto the mounting posts
Reinstall the fan using the original screws
This mod improves airflow efficiency and helps keep the MCU cooler on affected K1 models. A quick and easy upgrade where the gap exists.
It seems there is 2 types of fans, you mat notice the fan on the right in indented holes to allow for a closer fit to the base plate. It still leaves a gap. This plate works with both fans.
This was how my fan looked prior to the mod. A 4mm gap, which the fan would basically recirculate air.
This is after, noting the fan essentially sits flush with the base plate.
