I3 Mega Hotend Cover

I created this cover about one year ago. Since then i use it successfully with my i3 mega.

No gluing or assembling necessary, but supports.
Closed design with airflow upwards.
Make sure the screws are the right length.

I use a Noctua NF-A4x10 FLX as hotend fan:

As component cooler I use a Sunon Radial Fan 50x50x15mm MF50151VX-A99:

I use the airduct from formateins because I didn't have any good experiences with the ring fan duct's.
