Air Duct for SecKit SK-Tank with Fly CDY v2 Controller Board

thingiverse

Here's a fan duct for a 40mm fan to blow air across the row of stepper motor drivers on the Fly CDY V2 3D printer controller. I'm using this set-up on an SK-Tank printer but I've designed the duct to mount to two of the same screws that mount the Fly CDY V2 board, so this design could work for other printers that use that controller. I may add an optional nozzle extender that ducts the air all the way across the six stepper motor drivers for better cooling efficiency. Let me know in the comments if you are interested. Printing: Orient the part such that the outlet of the nozzle is pointing up. No support necessary. I printed it with four walls and 20% infill but these settings aren't critical. 5/31/2021 - Updated this design to "v2": enlarged the outlet of the nozzle for better airflow, redesigned mounting tabs for no interference with Fly CDY controller board and other minor dimensional changes for quicker printing.
