Inspiration:

After installing the K1 Series CFS Upgrade Kit on my K1C, like many other users, I didn't like the fact that purge waste simply drops to the bottom of the printer. I wanted a solution that wouldn't require modifying any factory parts or cutting into the back panel.

While searching for options, I came across Peter Healey's "Creality K1/K1C/K1SE with CFS Purge Poop Catcher." Although I liked the concept, I encountered some issues with his model's wall design. Inspired by his idea, I created my own version with a larger capacity bin, a magnetic mounting system that attaches securely without any modifications and added some Creality love.

IMPORTANT: This was designed to maximize the volume of the waste bin and is a tight fit. If installed properly, there will be no clearance problems. After installations is complete, move the print bed using the control screen from the bottom position through it's travel to the top. Watch at each step to make sure you have clear cover between the table and bin through it's entire travel. If the front of the bin is behind the behind the front of the lead screw cover as shown in the pictures, it should be clear of the bed.

Features:

No printer modifications required
Simple drop-in installation
Magnetic attachment
Large waste collection bin
Clean, integrated design

I've included the Creality badge and logo as shown in the pictures as well as several other options including blank badges for personal customization.

You can also go badge-less if you prefer a cleaner look. Just delete the negative parts from the bin in your slicer.

Versions

V1.1 (06/07/26): Initial Upload

V1.2 (06/08/26): Revised Bin model to remove the seam line on the front of the bin. Added a few more badge options.

BOM: (links are suggestions and are what I used for this project)

ABS or similar heat resistant filament
(8) - 8mm x 2mm Magnets https://www.amazon.com/dp/B0D577T64H
CA Glue https://www.amazon.com/dp/B0DYPFS2GL

Instructions:

After your parts are printed, glue the 8mm x 2mm magnets into the magnet locating tabs. 4 magnets are required for the bin and 2 magnets for each bracket. Make sure you get the magnet polarities correct before gluing them in.

If you are applying the Creality badge and logo, glue the parts to the bin using CA glue or ABS slurrry (acetone and abs mixed to a syrup consistency). The ABS slurry creates a stronger bond but takes longer to cure. Whether using ABS slurry or CA glue, a very little amount goes a long way so apply sparingly.

Brackets

Lower the print bed to the bottom to make room to work.

Tuck the left tab of the brackets behind the lead screw cover (black pastic cover provided in the upgrade kit). Make sure the upper bracket is above the the stepper motor wiring as shown. Snap the brackets onto the vertical wiring rail at the back of the printer. Don't worry about exact locations right now. We'll adjust them in a bit.

Bin

Place the bin in the printer with the bottom of the bin just resting on the angled motor cover from the CFS kit. Slide the brackets on the wiring rail up/down to line up with the magnets on the bin. You'll feel them connect when lined up. Remember to take care of the stepper motor wires at the upper bracket. There's a notch in the upper bracket to clear the wires.

Final position should have the bin just resting on the angled motor cover.

Installation is complete!!! Let me know if you have any questions and I'll do my best to answer them. THANK YOU FOR LOOKING!!!

Don't forget to check clearance between the print bed and the bin before normal operation.

Let the CFS prints rip!!!
