Anet A8 - Brush holder for cleaning the nozzle, reverse

thingiverse

This is a wire brush holder for an Anet A8, although it can work with other printers. Using a custom startup script in the slicer software will allow you to clean the nozzle exudate before each print run begins. The brush can be purchased at most box and hardware stores. The brushes usually come in a three-piece package that includes a steel bristle brush. I wouldn't recommend using that one. Use the brass bristle brush instead.
