Maturity: Good.
- 8 prototypes.
- In use since 2024/10.
Wanted something for an MK35 as the original MK4 is too thick. The MK4 version collide with the X stepper motor.
Hardware:
- (x4) M3x10 screws are nice. Domed head are better.
- 4010 24V fan
On my MK35, I connected the fan to the bed heater output. Then the fan run only when the bed is heating.
Don't know which is better for air flow. Exhaust or Flow inward. for a proper exhaust, we should put the fan at the top. For a flow inward, we should send flow to the MCU. It is then best design but it is good enough to move some air and decrease enough the buddy temperature.
Log:
- 2025/03/20: Moved the fan to the left of the electronic box.
