A replacement part cooling duct for the K1C and K1 SE, shaped to funnel air at the tip of the nozzle rather than spraying it across everything on the plate. Concentrating the flow there is what tightens up small perimeters, short bridges and raised lettering, and it leaves the rest of the model alone so tall parts do not chill unevenly. Fitting it counts as light maintenance: switch the printer off, let the toolhead go cold, take off the existing shroud and secure the duct in its place. Run a calibration print afterwards to check clearances and settle your cooling profile.
Good for
- Crisper text and small features
- Reducing stringing on detailed prints
- Short bridges without droop
- Upgrading stock K1C cooling
