AD5M Improved Heatbrake Cold Side Fan Duct

CC-BY 4.0, have fun, make good use of a small mod that really helps the AD5M be consistent. 
Inventor, DWG, and STL included for 12mm(v2) and 14mm(Conch) heatbrake sizes.

Print the largest you will need, if unsure, print Conch. Honestly, probably just print Conch.

But if you only use the cheaper V2s, it will get just a bit more outa them with its version.(conch will even fit, just a bit tightly)

This mod does: Maximize what the 3010 heatbrake fan can do for the cold side of the hotend. Especially useful if running high temps.
This mod does not: Help if your ambient chamber temp is too close or above the temps your filament cant feed under. This will still cause heat creep/jams without forced cooling of some kind or reducing chamber temp.
This mod does likely: Give you more leeway thanks to increased airflow where its needed.

Print settings: 0.4 Nozzle, 0.2 layer height, standard walls.
ABS or higher HDT pref, though PETG will do in a pinch. PLA will probably warp.
No supports, design is built to accommodate printing on its own. Print was about 5 minutes and 1.5 grams of filament for me.

Install: Requires taking out the extruder as you would to service it. Chose a shroud sized for your largest heatsink, you don't want to be swapping shrouds--its not a fun proccess. Conch=14mm, V2=12mm, Stock/V1/such=10mm. If unsure, use the conch sized duct as it will accommodate all current hotends. One 2.5x2.5x15mm press fit square peg goes in the bottom front holes, though an appropriate screw could also be used. Sqrew holes are 3.5mm on the fan and model as provided. The top edge has a tab that nestles between the fan and extruder in a very convenient gap. Does make inserting the extruder a little more awkward, as it leaves less free space. But I had only the slightest trouble with it.
