Nozzle wiper brush

I got more and more print fail due to some leftover on my nozzle I know it's about time to change my nozzle, but somehow I just want to extend its lifespan a bit more so I just design a nozzle brush for a quick easy cleaning it use two A1 nozzle brush just move the tool head forward and brush it few time while hot that's a fail print because of dirty nozzle
