Support and Fan duct for Solidoodle 4 (with new extruder)

This is a fan duct and a support for the Solidoodle 4's new extruder. The support can be used for mounting anything (gauge, ...).
I'm still working on this design cause the air flow is not powerfull enough and the duct is to close to the hot end so it starts melting after a long use.
If you have any idea to improve this design, feel free to let me know!
