Prism Duct

This Prism Duct is designed for those who want to add 5015 fan but no longer want to change the enclosure

this design utilizes the stock metal enclosure

v3 update
-duct was lowered 4mm, its now 2mm clearance to the bed.

Note:
No CFD study is made,
if you think stock fan design is ok,
then this mod is just a little step up.

feel free to comment any feed back.

small tips will be appreciated :D
