SV06 Plus Extruder Backpack - PC4-M10 & 4020 Fan Mod

The SV06 Plus (and probably also the smaller SV06) Extruder Backpack:

Add a PC4-M10 fitting as well as a upgrading the stock fan to a 4020 all in one piece.

You will need 3x M3 Nuts and 3x M3x20 screws, and the PC4-M10 fitting. And the 4020 fan, of course. You will also need to replace the one extruder mounting screw out and use an M3x6 screw.

This remix combines the original model with @Samuel_294045 ‘s remix of @yetzt ’s 4020 fan mod. 

I made these changes mainly because I wanted to use 2 original mouting screws for the extruder assembly to keep it well aligned, plus using the other 2 screw holes on the side under the hotend fan makes it feel more securely attached than using the orignal PC4-M10 mod's design. Also I only had PC-4 M10 fittings around, so I changed the hole size on that part.
