Anycubic cooling exhaust vent

I upgraded my Anycubic Linear Plus to the TMC2208 stepper drivers and printed the cooling tunnel designed by Ivanmartin18 (https://www.thingiverse.com/thing:2431556). I don't like the cooling fan blowing under the heatbed so I made a ventilation duct to direct the air outside.

In the photo you can see Ivanmartin18's original cooling tunnel. The duct is the extra bit on the right-hand-side of the cooling fan.

This is designd for the Anycubic Linear Plus. It will be too long for the non-plus
