After trying to fit the best Filament Cooling Fan I've seen I found it wouldn't quite fit.
As a result I have made 2 versions.
One is a corrected version of the best found on thingiverse.
The other was modified from another full circle originally designed for a different machine.
Unfortunately I do not have an original file for the new blower fitting so can not make a version for it.
v2 is a corrected version of Tronxy X5S Filament Shroud by SummersideGuy, published Nov 23, 2017
v3 is Based on Hesine M-505, Anet A8 - Center Nozzle Fan by Arjjck, published Jun 13, 2016
