Smart Effector Fan Duct 360

I wasn't happy with the cooling performance of the conventional fan duct on my Smart Effector. Especially on small parts the air wasn't coming close enough th to nozzle tip to effectivly cool the part, additionally the cooling effect was different on all sides of the model.

Design goals:
- airflow as close as possible at the nozzle
- equal cooling on all sides
- simple mounting, if possible single part design
- include 40mm hotend fan adapter for silent operation

It's a single part print without support which attaches magnetically to the screws/nuts on the extra mounting holes on the smart effecor. So these can still be used for mounting i.e. a zesty nimble (like on my printer) and the assembly can be taken off within seconds.
For part cooling i'm using a blower fan because high pressure is needed which axial fans do lack, i used a 50mm one but 40mm might work, too (couldn't find one locally which was specified at 24V)

This totally CAN be printed using PLA, but make sure
