This model remixes the right rear riser from the original “JC-Creality K1 Lid Riser” by Joe Cooper which must be printed for this to be useful.

The rear mounted filament spool holder on the Creality K1 is inconvenient if not downright unusable in certain printer configurations such as up against a wall.  This mod relocates the filament run-out sensor to inside the printer which affords a number of benefits:

  • much easier filament loading
  • multiple filament mounting options with side load entry
  • eased path for the reverse bowden tube so that it naturally follows the cable chain without sharp bends
  • reduced length of reverse bowden tube thus a shorter stub after runout
  • fully closed chamber when printing ABS

Because the reverse bowden is no longer exiting the rear of the printer, the gap can now be completely closed with the provided “betweener”.

The original Lid Riser design is genius.  Install all “betweeners” to close the chamber retaining heat for printing ABS, ASA etc, or remove the “betweeners” to ventilate for printing PLA.  The “betweeners” are flat and store easily in the bottom of the chamber.

Spool Mount Options:

  • any free standing spool holder
  • above using the TUSH rollers
  • side mount spool holder for K1
  • filament dryer
  • 5kg spools on floor

Directions:

Remove the filament run-out sensor from the printer and mount it to the new riser with the connector facing down using the existing hardware.  You are screwing into plastic and the threads are very short so don't over tighten.  Fish the sensor connector back into the cable tray then run it upwards out the top and connect it back to the sensor.  The existing cable is long enough to reach so no electrical modifications are necessary.  Then attach the riser in place with an m3x30 bolt.  Thread bowden tube through cable chain and cut to length.

Updates:

  • Nov 14. 2023 - Version 2 tweaked to avoid collision with extruder (thank you SYNTAXV)
  • Nov 29, 2023 - Although I can't use it due to no clearance above the printer, I've included the part for the hinged top
  • Dec 4, 2023 - Users @FabioDias_488006 and @pellcorp pointed out that the rear betweener was not sitting flush - I've uploaded a corrected part
