This 3D model is a practical waste box and purge block system designed to collect discarded filament during nozzle priming, cleaning, or material changes on a 3D printer. The waste box provides a dedicated space to catch and contain filament strings, blobs, and purge lines, keeping the print bed and workspace clean. The accompanying purge block allows the printer to extrude excess material in a controlled area, ensuring the nozzle is properly primed before starting a print.

The waste box is compact yet large enough to hold multiple print sessions’ worth of filament debris, while its smooth walls make it easy to clean out. The purge block is dimensioned to provide sufficient surface area for the nozzle to wipe and deposit filament, preventing contamination of the main print. Both components are optimized for quick and efficient printing, with sturdy walls, consistent thickness, and a geometry that minimizes the need for supports.

This design can be printed in PLA for standard use, or PETG/ABS for higher heat resistance, especially if mounted inside a heated enclosure. It can be scaled to fit the specific build volume or maintenance routine of the user. The waste box can be placed on the print bed, mounted nearby, or positioned within the printer’s frame, depending on personal workflow.

A waste box and block setup is an ideal accessory for makers who want to keep their 3D printing environment tidy and maintain consistent print quality. By providing a dedicated place for filament purges and scraps, it reduces cleanup time, prevents print defects, and keeps your machine operating smoothly.
