This is a clip to be used in conjunction with a brass wire brush head. The particular brush I'm using is from Harbor Freight (Item# 69638). I find this works better at cleaning the heads before and after a print than the thin metal blade and piece of rubber the printer comes with. Should work with the DaVinci 1.0, 2.0 or 1.0 AiO.Utilizing a small brass wire brush (mine was from Harbor Freight Item# 69638). Once you have printed the clip and cut the head off of the brush, slide the brush head into the clip. Slide the clip into place on the dump bins. You will want to trim the brushes down to just above the metal cleaning blade that comes with the bin. Leaving them full length is too much drag on the head. This can be done with normal scissors.
