MINI-z-top With filament holder

This part is composed of the original default part with an extended arm, designed to hold the filament pully in place while printing.

The installation process can look a little intimidating but it's quite simple.
First, remove the screws in the top part which hold in place the part to the aluminum z-height part, and the screws involved in the tightening of the guide rods as well as the motor screw.

After completing that disconnect the z-height motor from the 
motherboard (the wire will be labeled z), and lift the motor until its possible to unscrew the
x axis from the bottom of the z-height screw rod, after that remove the motor and proceed to replace the MINI-z-top part with the new capable of holding the filament.

Afterwards assembly is easier, follow the steps above and start with the threading of the 
x axis to z-height screw rode.  

The difference between this part and the original is not much, other than extending one of the sides so it'll be able to hold filament.
