MK3S Extruder for Prusa Mini

I had an idea the other day..... wouldn't it be cool to port over the dual gear extruder and filament sensor of the i3 MK3S onto my Prusa Mini?

Well, now you can.

See it in action here: 

The firmware for this mod is over on thingiverse, you'll need to cut the appendix to flash the firmware: https://www.thingiverse.com/thing:4761746/files

With the new 4.3.3 firmware out, you don't need to cut the appendix. Just change the steps/mm to 140. 

So instead of shelling out big bucks on a bondtech extruder, now you can get both the extruder and filament sensor in a compact package for under $60 (cheaper if you settle for the chinese bondtech knock-off gears, which I don't recommend).

If you want to chain up all the way through to the hotend, here's the chain and hotend bracket: https://www.thingiverse.com/thing:4614287
-Just don't print the extruder body, it's not needed with the MK3S design.
