Used the front dual fan duct by DrLex for a couple years but kept having issues with cooling on the back side of my models

I wanted a nice wrap around vented Duct for even cooling on both print heads.

/////////////////
Version 1.2 started warping after 50 hours of printing at 220 Celsius

\\\\\\\\\\\\\\\\\

v2: No warping so far after another 50 hours of 215C printing.

Even cooling via interior ducting.

C&C greatly appreciated!
Please enjoy!
