CREALITY K1 | K1C | K1SE - LID RISER V3 [FRAME EXTENSION KIT]

LID RISER V3 [FRAME EXTENSION KIT] | Vents | Filament Sensor | LED Strip | Hinges | Embedded LID

*If you have any issues with printing or assembly, feel free to message me, and I'll do my best to assist you 😉.

*Because of the seam inside the walls, the internal space is reduced. To clean it up, use scissors or a similar tool. Simply insert the scissors into the wall and go back and forth a few times until it feels cleaner and there’s no more resistance. This will ensure the vents will slide.

*If it's difficult to slide the pieces together, use a metal file to clean the rails, especially on the wall pieces. This minor adjustment can make a big difference. The fit is meant to be snug, so the pieces aren't loose. I had to do this with some of my pieces. Some fit perfectly, while others were tight, likely due to the printing process. Just file the rails a few times, and they should fit perfectly.

/////FOR THE K1SE

• The K1SE frame does not include the 4 threaded holes in the corners, so the riser cannot be mounted in the usual way. Dennis Mckinney created this solution, which I’m sharing here.

UPDATE 0.9 15/07/2025 - GUIDE UPDATED WITH THE BOM LIST FOR CFS MOUNT V1 AND V2 VERSIONS

UPDATE 0.8 26/06/2025 - NEW TEST PARTS FOLDER
These parts were created to test the most critical fit between components before printing the full model.

• Start by printing just two test pieces and check if they snap together correctly.

• Confirm key dimensions and adjust your slicer scaling if material shrinkage is affecting the fit.

• Once everything looks good, print the remaining test pieces to be sure your printer is dialled in.

If the vents do not slide properly into the wall, even when the size is correct, there might be small bits of plastic left inside the channel from overhangs or bridges.
To fix it, use a metal tool like a closed pair of scissors and run it through the slot from end to end.
Keep doing this until the path is clean and the tool moves freely. That should restore smooth movement.
 

UPDATE 0.7 09/06/2025 - NEW VENTS VERSION – CFS COMPATIBLE

FOLDER - VENTS_VERSION - CFS COMPATIBLE

FILE - [c]_x4_K1C_V3_VENTS_CFS_VERSION.STL

This updated part was designed for users who have the CFS system installed on their K1, K1C, or K1SE.

When the CFS is mounted, the printer loses about 5 mm of travel on the Y axis. That means even if the original vents part fits on the build plate in the slicer, it will fail during printing because of that shift.

To fix this, I created a shorter version that stays within the usable print area.
The original design had a wider side flange, which helped seal the riser more effectively. Since that width is no longer possible with the CFS in place, this new version keeps just enough material to maintain a proper seal for materials like ASA or ABS.

UPDATE 0.7 16/05/2025 - NEW BACK WALL with FILAMENT SENSOR INVERTED
This version allows you to install the filament sensor upside down.
The sensor is not directional, so it works the same way when inverted. With this configuration, the cable connector is positioned at the bottom, which means you can use a much shorter cable.

*INSTALLANTION INFO - FILAMENT SENSOR CABLE 

If you’re having trouble connecting the filament sensor because the cable is too short, start by removing the printer’s bottom cover and cutting the zip ties holding the cable in place. If it’s still too short, it’s likely glued inside the raceway. In that case, you’ll need to remove the entire cable cover and carefully free it from the superglue.

UPDATE 0.6 30/01/2025 - New Chain Wall

In this new version, the vents on the inside of the wall have been partially closed to eliminate the noise that occurs when the chain rubs against them during operation.

UPDATE 0.5 19/12/2024 - New closed wall version

UPDATE 0.4 | 22/11/2024 - Filament sensor wires

To get more slack for the sensor wires, you just need to remove the bottom cover and cut the two (usually) zip ties holding the wires in place, and you’ll have enough slack.

UPDATE 0.3 | 03/09/2024 - Material quantity by color

[a] - Polymaker PolyLite ABS Galaxy Dark Grey - 128.39g

[b] - Polymaker PolyLite ABS Black - 383.06g

[c] - Polymaker PolyLite ABS Green - 83.1g

UPDATE 0.2 | 14/08/24

Check this video for fine-tuning filament settings and dimensional accuracy:
 https://youtu.be/7BUJLbQUABY?si=EGsZtkVig8zLeMMX 

• If the sensor cable is too short and you can't connect it to the sensor, you'll need to remove the bottom cover of the printer, and you’ll see some zip ties holding the cable in place.

NEW INSERTS

The inserts have been updated. The 5mm inserts left marks on the frame's exterior, so please use the new 4mm inserts instead.

SLIDING

For smooth sliding like in the video, use scissors or a metal object that fits inside the walls. Move it back and forth several times. This will clean up the internal overhangs that cause the slider to not move smoothly.

RISER FEATURES:

• MOUNTING SYSTEM: The parts are secured together with bolts and inserts. The only glued part is the flap that closes the cut-out on the back of the LID.

• VENTILATION: It has 360° ventilation, the highest ventilation I have ever designed in a riser.

• EMBED LID: The LID is embedded in the frame, giving a cleaner look. Despite being embedded in the frame, the usable space inside the printer is the same as the V2 50mm [another of my projects].

• HINGES: The hinges open 110° (allowing printing with the LID open) and have an inner flap that ensures alignment of the LID with the frame.

• HANDLE: It has a handle (press-fit, but I have a version with a fixing tab for the LID if needed in the future).

• LIGHTING UPGRADE: There is a predefined space for an LED strip. One of the inner corners has a fixation point for the wires if LEDs are installed.

• FILAMENT SENSOR REPOSITIONING: Fixation points on the back wall to place the filament sensor inside the riser. One of the side wall parts has a hole for the PTFE tube.

• CHAIN ADJUSTMENT: Mounting points on the back wall for the piece that allows adjusting the chain height.

/////THINGS to ADD

• Front Chain Riser (12mm) - LINK

////ATTENTION

• Make sure the bolts aren't too long. They shouldn't go past the frame's thickness to avoid damaging any internal components. [ The bolts listed have been tested ]

/////IMPORTANT

• Before starting the print of the riser, I recommend printing this tool https://www.printables.com/model/899470-xyz-accuracy-test-calibration-tool to test the dimensional accuracy of your printers.

• Use this tool https://www.printables.com/model/480907-shrinkage-calculator-dimensional-calibration-tool to determine the correct scale based on the filament shrinkage you’ll be using.

• The riser pieces were developed with very tight tolerances (0.2mm) to ensure proper alignment and functionality of the assembly, so it’s important to make sure everything is well-calibrated or that you understand what is needed for everything to work correctly.
