FLSUN_SR - Y duct for deported blower system like CPAP

This is a Y-shaped duct for a dislocated cooling system (similar to CPAP) for FLSUN SR. This duct is suitable for those who, like me, use the NSK Superfly type direct extruder (https://www.thingiverse.com/thing:5203540). The model is available in 2 versions: 1 for smooth interlocking tube 2 for oversized spiral tube.
