Anycubic Mega S Even Flow Circular Fan Duct by Racoon2020

Last crawled date: 3 years, 5 months ago

Work in progress, do not print those files yet, they won't do ! (will post final design in a few days, encourage me in comment):
Currently head centering is still off center
Need to reinforce fan holder
Need possibly some increase of roof height of the helix to be air tight
Provide final washers design
Design objectives:
Perfectly centered around head
Even flow distribution
Most powerful blow possible
Optimal design for FDM printing
As no such fan duct already existed I designed my own.
The air duct reduces its section linearly to keep pressure constant through the 24 holes (using helix shapes).
Let me know in comment what you think.
Works probably only for Anycubic Mega S. Assume original fan or equivalent 45mm radial fan duct located in original place.
The picture shows the vortex effect with water, really nice :)
