Cleaning off your hot end can be a messy and dangerous task when dealing with tempratures of 200c. Many people choose a brass brush to clearn their nozzle but the downside is that picking filament out of a brash brush is nearly as painful as removing the hot filament with your fingers from the nozzle.
The ultimate nozzle brush to the resuce!
The Makers Mashup nozzle brush uses felt furniture pads to clean your nozzle quickly and easily. Felt pads made from natural materials can hold up well to the heat. Even polymer based felt pads can be used as long as care is done to ensure the pads to not remain in contact with the hot end very long.
All that is needed is a quick scrubbing wipe with the nozzle side. A few swipes and your nozzle will looks as clean as the day you bought it. The flat pad can be used for a quick wipe right before a 3D Print to grab that ooze you encounter when warming up a printer.
When your pads wear out, just pull them out and replace them with a fresh batch.
