Buy an affordable dish scrubber, similar to the one pictured, featuring "Mexico fiber" bristles. This type of scrubber can be purchased for approximately $1.49 at a local hardware store. The "Mexico fiber" bristles are heat-resistant up to 200 degrees Celsius and can withstand even higher temperatures if the hotend is moved slowly across them. Carefully remove each bunch of bristles from the brush. Place each bunch into the printed mount designed specifically for this purpose. Assemble all components together, adjusting the position as needed to achieve optimal results. Write a custom START G-code command to move the hotend slowly back and forth across the mounted brush. Enjoy the satisfaction of having a clean hotend.
