This is a fan shroud designed to be used with my EZStruder carraige for the Robo 3D. I'm posting this separately in case someone wants to try to use it in other installations.
This fan shroud prints fine without support. It is designed to mount to a fan mount with two screws and the shroud mounts with the other two. Feel free to use the f3D file to make your own derivatives.
FYI, I printed it big side down.
