Forced air fan duct for Zonestar P802Q

I like to watch what is printing, so I designed this forced air fan duct to give a good view of the print area combined with good cooling, you need a 50 x 50 mm fan to mount into this. coooling is great for both single and dual extruder

Version 2 now also attached. I changed nozzle and throat and found my original design was now cooling the heating block! This version is slightly taller, also I have the airflow jet closer to the print. If it is too low for your set up you can add washers or
