Bento Box v2 fan duct for Creality K1 | K1C

For those with the K1 model, I have specifically crafted a fan duct that conforms to the real-world constraints of this model. It attaches to the lower frame of the printer, requiring only the substitution of the original screws with longer variants (M4x8 or M4x12) to accommodate the added component.

Where to buy the items: Since my links become outdated, please refer to the original post. There are links for the 4020 Fans, HEPA Filters, and Magnets.

HOW TO RUN THE WIRING: 

If you have bought the fans from the Aliexpress link above they should have the correct connectors. 

Connect the fans in parallel and run the wires through the duct as shown in the picture below: 

Then connect the fans to the PA0 connector. 
Please refer to this motherboard pinout link to connect it properly. https://github.com/CrealityOfficial/K1_Series_Annex/blob/main/pin%20out/motherboard-pinout.JPEG

Once you have it connected like this you will need to add this block of code to your printer.cfg file:

[output_pin bento]
pin: PA0
pwm: True
cycle_time: 0.0100
hardware_pwm: false
value: 0.00
scale: 255
shutdown_value: 0.0

Then you should be able to control the bento from the Mansail/Fluidd interface! 

For users using OrcaSlicer here are the material settings to automatically turn on and off the bento for the print!

The fan duct is shorter and has different holes than the original ones for other printers provided by the creator.
