This is a remix of hadoko's Anet A8 Extruder Fan Modification V2
See thing for more details: https://www.thingiverse.com/thing:2290361

Alterations:
This part was completely remodeled but uses the same working principles as the original, notable design changes include: hinge is mounted on the inside of the fans; heat-sink does not hinge with the fan (I find that being able to see the loading of the filament through the hole in the heat-sink is more than enough of an aid); does not require any modification to the stock parts.

Required Fasteners:
x4 - M3 x 25mm SHCS (2 req'd for part cooling fan, 2 req'd for extruder motor mounting)
x2 - M3 x 18mm Machine Screw (mounts fan to hinge)
x2 - M3 Hex Nut (mounts fan to hinge)
x2 - M4 x 14mm Machine Screw (mounts clip lower bearing)

Notes:

• installation requires complete removal of extruder to access linear bearing screws
• slots allow for adjustments due to variations in assembly
• parts should be rotated to allow for printing without use of supports
