Anycubic i3 Mega E3D v6 X-Carriage [MK4] Circular fan-duct for blower

thingiverse

A friend had trouble with the cooling efficiency from the A fan duct of the Anycubic i3 Mega X-Carriage [MK4] so we were looking for a circular duct to adapt. Found lukie80's and used it. At this moment it's a work in progress! Use this at your own risk, it hasn't been thourougly tested. Because of the heater block size and nozzle offset placement of the E3D v6 hotend, the duct is offset by 1 mm and there's a hole where the heater retaining bolt touched the duct, hopefully the clearance is enough to avoid melting. Since the authors bothered to upload the STEP files, I did the same. There are two versions of the STL file, one with the original supports from by ML3DPrinting, one without, in case someone wants to print this in a different position.
