Vertical Fan Duct Universal Rear Electronics Case for Ender 3

I was half way through designing my own SKR v1.3 case, when I saw Micheal with Teaching Tech's awesome "Ender 3 All-in-one, Universal, Rear Mounted Electronics Case". It had everything I needed and wanted in a case - Raspberry Pi, Buck Board, SKR v1.3 and compact design.

For my configuration, there was one little draw back. My Ender 3 sits on a foam mat to help reduce vibration and noise. The fan exhaust blew directly down into the foam mat, causing poor circulation.

I did not want to redesign the whole case, so I noticed there was just enough room to angle the fan at 23 degrees and blow air out the bottom and the back. So after a few modification in Tinkercad, I carved out enough room for the new exhaust on the left side and on the right side I added a few matching in flow vents as well.

The remaining pieces, the covers, are available in the original project below. I hope you don't mind Micheal, you did a great job in the design of this case.
