Add fan duct / shrowd STL model for 3D printing

[dracid]

Hello FW team,

it would be great if you could add the 3D model for the fan duct. I'm trying to print more transparent parts and hope the translucent PETG duct can help more light shine through <3

Also, this would be useful in case someone lose/damaged their fan duct.

Thanks and regards
-G.
