Creality K1C upgrades

Most of these K1C mods are community designs from Printables that fix small annoyances: a low lid, a drafty door gap, and a nozzle that the stock routine cleans slowly.

Printed mods

Mod	What it does
Lid riser v2, 35 mm	Raises the lid for room above the toolhead and a path for an LED strip. Vent and sensor versions of each wall.
Bowden clip for the lid riser	Keeps the Bowden tube clear of the lid.
Door hinges	Replacement hinges with a 0.2 mm print-in-place gap.
Door seal	Front and back plates with 3 mm foam to close the door gap.
Hygrometer door mount	Round holder for a small hygrometer on the door.
K1 Max fan mesh	Guard over the fan opening.
Side fan protector	Grille for the side fan.
HSW right panel	Replaces the right panel with a honeycomb storage grid and a spool holder.
Nozzle brush mod	Bambu A1 brush in a printed holder, plus a faster wipe macro.

Faster nozzle wipe

Creality does not sell the K1C brush on its own, so the nozzle brush mod uses the Bambu A1 brush. The holder must be printed in PETG or another heat-resistant material; PLA melts where the nozzle touches it.

The stock CX_NOZZLE_CLEAR routine works but moves slowly. The mod replaces it in START_PRINT with a short macro that scrubs left and right five times:

[gcode_macro NOZZLE_BRUSH]
description: Faster and wider horizontal nozzle brushing
gcode:
  G90
  G1 Z10 F1000          ; raise to a safe height
  G1 X110 Y224 F5000    ; move above the brush
  G1 Z3.5 F600          ; lower onto the brush
  {% for i in range(5) %}
    G1 X95 F4000        ; swipe left
    G1 X125 F4000       ; swipe right
  {% endfor %}
  G1 Z10 F1000          ; lift off

Back up gcode_macro.cfg before you edit it. Changing it needs root SSH access on the K1C, and a firmware update can overwrite it.

The smart upgrades page covers the status light, fume extraction and camera I plan to add.
