Replacement rolls for Numatic Herny Freeflo Floor Brush

prusaprinters

Sometimes the easiest designs just do wonder :-) Our Numatic Henry mostly equipped with the flat “Freeflo Floor Brush”; however, the small rolls wore down. These exchange rolls are: slightly wider and larger, but still fit perfectly in the original spaces in the brush. Using PETG, ABS or ASA should be durable enough.   Use a nail (or similar) and a hammer to carefully push the roller pins from the outside pointing to the inside, and then exchange and pry back into the plastic. It is just about the same technique as with connecting wristwatches links, just a little larger.
