Ender 3 screw cover

thingiverse

It's a custom cover designed to protect both the Ender 3 Z-axis screw and the dust filter that collects debris from your filament. This clever design ensures that the delicate screw remains free of contamination, preventing the buildup of grease and grime. By wiping away dust particles as they accumulate, it maintains a clean and efficient printing environment. The cover securely fastens with standard screws, eliminating any need for additional hardware or modifications.
