Added mounts with larger pin offset (*_low.stl). They allow to move the blowing vents closer to nozzle tip then originally designed by @dpetsel in Petsfang duct. For my taste they are a bit to high.
Added thickness to walls around mount holes.
Uploaded correct connection bar.
Added photos of assembled part on printer
This is a very compact, double fan duct for Creality Ender 3 / CR10 printers.
It is designed to mount on base mount from this Petsfang Duct by @dpetsel:
general idea is based on @RaffoSan double fan duct:
but all the parts are modelled new, except joint bar that is a longer version of the one found in original.
Mounting points are detachable, to allow easy modification and adaptation to other base parts. Guleing required.
More pictures of printed parts and mounted on printer are coming soon.
Suggestions and feedback are always welcome.
