DaVinci Printer Cooling Fan Duct 40mm Fan

I was in need of a cooling fan duct for my Davinci and really liked this design by the user oscahie. The only issue was I had a 40mm fan and not a 50 as this was originally designed to hold. So I brought it to Tinkercad and modified it to fit a 40mm fan!

PLEASE NOTE: The screw holes for the fan are still that same as if it were for a 50mm fan. The only thing that is different is the size of the fan hole for airflow.
