About

For the Mosquito hotend, this mod shortens the Afterburner tool head by 10mm along Y. It reduces weight at the maximum lever point on the tool head and gives an open duct so you can service the interior in case of a dropped screw or similar.

You will switch to a smaller layer fan for weight and size benefits, at the cost of maximum air throughput. For ABS, ASA, Nylon and other low-fan materials this is often sufficient but you may struggle with PLA.

There is an option for a prettier 40x10 (the one from 2.2) and a lighter, more utilitarian 50x10 which is better on all counts except cosmetically.

STLs

File	Note
blower_case.stl
blower_lid.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	You might need supports. I used supports on the duct seal wings to keep them a little nice.
v_5010_case.stl	For ugly 50x10 style. Replaces blower_case.stl.

Assembly

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)
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. (5010 does not have heat set inserts on the "lid")
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. (5010: grab a 3.3mm-ish bit to make your fan holes pass a 3mm screw through)
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 and not need to.
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)
Mosquito-only.
PLA is hard to use with low CFM layer fans.
