Anet A8 direct drive replacement/extension carriage (MK8 extruder compatible)

This carriage is designed to:
- Replace the original carriage by providing a maximum of compatibility with original parts (you only have to replace the fan duct, all the other original parts can be used)
- Provide similar positioning of the nozzle, so you not even have to change the firmware when coming from the original A8
- Provide ab platform for any direct drive design you want to put on your Anet A8
And the reason I did it:
- Provide the possibility to use upgraded extruder designs lik
