Refillable Activated Carbon Filter for Creality K1C

This is an extension for the model “Creality K1 – HEPA + Active Carbon filter housing”.
It enables the use of refillable activated carbon pellets as the carbon filter media.

How to print

(Example shown for OrcaSlicer, other slicers work similarly)

STEP 1

• Example shown for bottom.stl (same steps apply to top.stl)

• Place the model on the build plate

• Set the model center coordinates using world coordinates (important!)

• Note the X and Y values
  Example: X: 60.0, Y: 170.0

STEP 2

• Right-click the model

• From the context menu: Add Modifier → Disc

• Set the modifier cylinder diameter:

  • bottom.stl: max 60 mm

  • top.stl: max 66 mm

STEP 3

• Set the modifier cylinder absolute position in world coordinates

• Use the same X and Y values from STEP 1

• Make sure the modifier cylinder fully intersects the model along the Z axis

STEP 4

• For the modifier cylinder, set:

  • Wall loops = 0

  • Top shell layers = 0

  • Bottom shell layers = 0

• Configure infill settings according to your own preference and aesthetic judgment

Optional

You can add a support blocker for the thread on bottom.stl
(e.g. a 71 mm cylinder positioned using world coordinates).

Print settings used

• Wall loops: 5 (enough to fully fill the model)

• Layer height: 0.2 mm

• Material: any filament works, but PETG or higher temperature-resistant materials are recommended

Notes

• Original filters have a diameter of approximately 72 mm

• This model is intentionally made slightly looser at 71 mm

• You can adjust the scale to fit your preference

• For better dust capture, it is recommended to glue a fine mesh onto the filter using cyanoacrylate (CA) glue
