Tevo Tarantula Pro Box - Nozzle Cleaner for Dremel Brush

thingiverse

Use a dremel circular brush to clean the nozzle, the narrow brush makes sure the nozzle passes over the brush completely compared to other brushes i have tried. This design takes the idea from https://www.thingiverse.com/thing:4062294 though its not really a remix, it does use the mount part. Use a 25mm brush, cheap ones can be found on aliexpress and other places. Print the holder in the oirentation it will appear on the build plate, support is required. Then add a small nut and bolt to the smaller piece, insert the brush into the hole and assemble. You will need the mount part from https://www.thingiverse.com/thing:4062294 and attach the brush holder per the instructions from that. Adjust the position so the brush does not hit the print bed.
