Creality K2 Poop Chute / Filament Purge Chute

Description

This model is a rear-mounted poop chute for the Creality K2, designed to manage filament purge waste during multi-material printing.

When the printer performs filament changes or purging operations, the expelled filament ("poop") can accumulate behind the machine or fall onto the desk. This chute captures and guides the purge material downward, keeping the area behind the printer clean and preventing stray filament from piling up around the machine.

The design attaches directly to the rear panel of the printer using the existing mounting points and channels purge material through a smooth internal ramp, directing it safely into a bin or container.

The geometry was designed to ensure that purge strands slide down easily without getting stuck, even during long multi-color prints with frequent purges.

Features

• Designed specifically for the Creality K2

• Rear-mounted installation using existing screw holes

• Smooth internal ramp to prevent filament buildup

• Wide entry to reliably catch purge material

• Directs waste downward into a container

• Helps keep the printer area clean during long prints

Printing Recommendations

Recommended materials:

• PLA

• PETG (recommended for durability)

Suggested settings:

• Layer height: 0.20 mm

• Walls: 3

• Infill: 10–15%

• Supports: Not required

Installation

Print the model.

Remove the corresponding screws on the rear panel of the printer.

Align the chute with the mounting holes.

Secure it using the original screws.

Place a small container or bin underneath the chute to collect purge material.

Notes

This accessory is particularly useful for multi-color or multi-material prints, where purge cycles happen frequently and can generate a significant amount of filament waste.
