Anycubic 4Max Circular Fan Duct

thingiverse

Was trying to make a dual fan full circular part cooling fan duct but it didn't work well because of the space around the extruder on Anycubic 4Max So I ended up with this, I am not sure if it is better than the semi circular fan duct I posted before, I didn't test overhangs with it yet. I am also not sure if it deforms because of the heat block for the nozzle, but to keep it exactly in the middle I had to design like this and some parts are little close to the heat block, till now after some small prints I didn't see deforming. Added extra holes for cable management at the top part. Print with support, make sure you don't print supports in the air channels. I used 85° Support Overhang Angle on Cura 3.3.1 with no supports in the air channels in the circle.
