Ender 3 Filament guide/cleaner

thingiverse

This is a handy filament guide and cleaner I created specifically for my Ender 3 printer. Due to the abundance of dust in my print area, this tool helps keep it out of the nozzle, ensuring smoother prints. The cap clicks securely on and off with ease, allowing for quick access when needed. I designed this mount to attach to the top bar of the frame using standard T-nuts and M4x15mm cap head screws, which provide extra length where required. This makes it perfect for top-mounted spool and direct drive hotend/extruder set-ups. While it's primarily intended for these configurations, you can potentially adapt it to suit a Bowden tube setup by mounting it elsewhere on the frame. However, I haven't tested this yet. To use this cleaner effectively, place a couple of standard washing-up sponges inside the housing for cleaning the filament. Be sure not to pack them in too tightly, as this will restrict the movement of the filament and compromise performance. I printed this design with 20% infill using PLA at relatively high speeds, and it turned out exceptionally well.
