-upgrade #2

It's bin a while since the last update. Although not much has changed.
I've removed the previous update because it didn't work as planned.
The air outlet was to close to the print surface and destroyed a couple of prints. Another reason why I've removed it is because it's impossible to control the fan with the Gcode (it's always on).
I've been researching a way to make a controllable fan. I'll post an update when I've found a solution.
