BIQU H2 extruder part cooling duct with cable support

This fits the BIQU H2 extruder and uses a 5015 blower. I have it installed on an Ender 3 v1 but it should fit most printers with this extruder. I used zip ties to hold the fan on and also for the cable support. The cooling performance seems pretty good. Weighs 15g.

I have tried to incorporate these design elements that I wanted.

1. The filament release lever and gear is not obstructed.
2. Cable support.
3. 2 sided blower.
4. Clear view of nozzle.
5. High air flow, thus good part cooling.

Printing:

Standing in normal position. Normal print settings. Supports touching build plate only.
