Double fan cooling for Prusa i3 MK2 and MK2S

Since purchase of printer I had problems with steeper overhangs, sometimes it started to hit PINDA probe. I reworked newest B3 version nozzle-fan from MK3 but still didn't solved overhang problem. So I went to e3d-online shop and bought additional fan and V6 Silicone Socks and reworked MK3 B3 nozzle-fan design for dual fan setup.
Tested on temperature tower, with temperatures ranging from 190 to 220 degrees at 0.2mm height.
In photos left temp tower is stock MK2, on right dual fan setup.
SOCK ON NOZZLE IS MANDATORY SINCE COOLING PART IS ONLY ~2MM FROM NOZZLE. IF NOT USE SOCK, PART WILL MELT. Anyhow I can't guarantee that it won't melt where heater cartridge are located because it isn't covered by the sock and are 0.5mm apart, hope it lasts.
Parts printed from PETG.
Fan holder and extruder cover printed at 0.2mm, nozzle fan at 0.1mm. Extruder cover need support.
If you want quality I recommend turn on fan for nozzle fan part at least 30% speed since there are some steep overhangs.
No need to fully disassemble extruder. Just unscrew 2 front screws of heatsink fan located in left side of extruder. Unscrew 2 extruder cover screws located below stepper motor. Else you can figure out yourself :)
Cut off zip tie that holds wires at the bottom of extruder.
Original Prusa fan wire is short so I uncliped it from back of fan to get it bit longer and cut near extruder (I will do anything just to not disassemble everything). Soldered new fan wires near extruder and to old fan. Don't forget red wire to red, black to black.
STL files aren't properly oriented, sorry for that. There is photo that shows how parts need to be placed on bed.
STEP files included.

EDIT: Added MK2S extruder body with shorter PINDA holder to fit on MK2S version. Or you just could cut original one.
