+
+## What does it do
+* It gives you 7-10mm additional Y travel before hitting your front doors.
+* It reduces weight at maximum leverage, and reduces maximum leverage on your linear rail.
+* It lets you service your duct without disassembling your print head (did you drop a screw or piece of plastic)
+* It looks sick.
+* It's quiet and it moves plenty of air.
+
+
+## BOM
+* 6x m3x3.8 heat set inserts
+* 2x m3x12
+* 2x m3x16
+* 2x m3x20
+* 2x m3x30

+File | Note
+---- | ----
+[blower_case.stl](./blower_case.stl) |
+[blower_lid.stl](./blower_lid.stl) | 
+[duct.stl](./duct.stl) | You might need supports.  I used supporrt from platform only to keep the inside of the duct clean.
+[hotend_fan_cover.stl](./hotend_fan_cover.stl) | You might need supports.  I used supports on the duct seal wings to keep them a little nice.
+
+
+## Assembly
+1. You are replacing the front half of your print head.  You'll need to replace the front mosquito mount with the new shroud, so tear it down a bit (leave your clockwork intact, we're not messing with that)
+2. Put in the heat set inserts.  2 on top of blower_lid, 2 in the duct and the 2 on the backside of the duct for bolting the hotend case together..
+3. K sorry drill out the mount bosses on your neat little layer fan to 3mm, or snip them off.  They're in the way for your screws up top.
+4. And while you're disappointed, take a look at your 40mm fan.  The bottom frame edge around the screws might not clear the bolt heads of your 30mm lower shroud mount screws.  I snipped the frame corners a little for clearance but you might have smaller screws.
+5. Assemble the front of the print head like you normally would.
+
+
+## Known Issues
+* You might want some really lightweight foam to close your duct better if your print doesn't come out perfectly. (you'll see a little gap and know you want this or you won't see a gap and you won't care)
