Tiny slipover filamentcleaner

thingiverse

I designed a tiny filament cleaner to protect my hotend from dust and other debris that might enter through the filament. It's a simple device that slips right over the filament. To wipe away dust, I use a pipe cleaner wrapped around the filament and then stuffed into its small round case. I printed this design with 0.8mm side walls and a 1mm bottom, layering in 0.2mm increments. The only post-processing step required was to remove tiny printing nubs from the parts.
