I bought this item not to clean my 3D printer but as a tool for my work as a crystallographer. The bottle contains two different types of tweezers and two types of steel needles with different flexibility. These needles are flexible yet strong enough to remove fishing crystals from bottles very easily. While I can only imagine their effectiveness in cleaning a 3D printer for flexible yet strong needles, I can say it is a must have for their crystallographers. I wish there was a way to advertise this object as a scientific instrument, because it would sell like hotcakes in the crystallography community.
