Remix: MK8 Extruder Upgrade (Flashforge Creator Dual Extruder)

Remix of: http://www.thingiverse.com/thing:215739
This is for the Flashforge Creator Dual Extruder.

I found that the arms were 2mm too thick preventing the heat sinks from going back on correctly and worse, preventing the arms from moving with spring tension. So they couldn't function.

This remix has thinner arms. and 2.5mm less room for the spring giving it perfect tension force.
The other parts are all the same.
You will want to file down the pin heads after you put them together so that they are 2mm shorter too.
