i3 mega Spool holder for direct

I changed the i3 mega to a direct extruder, so I decided to place the spool holder and filament sensor on top of the frame.

The filament sensor wire must be extended with AWG24. Also, remove the iron ball of the filament sensor and attach it to the sensor bracket with an cable tie instead. The
cable tie should be loosened enough to move the sensor.

Things necessary
・AWG24
・cable tie(width 3.5 mm)
・6001Z Bearing
