Universal Wire Brush Holder for automatic nozzle cleaning

I couldn't find any wire brush holder that was suitable for my 3D printer, so I designed my own. Using binder clips was the easiest way to attach one. That makes this model semi-universal, and should fit most printers. My bed is about 7 mm thick, and I use small binder clips which are just the right size for it (19 mm wide, by about 7 mm thick) Thinner beds should work too, as long as the binder clips are a similar thickness, as the ends that are held by the binder clips are also 7 mm so that they are held in place securely by the clips. The brass wire brush heads I use are around 12.25mm wide x 40mm long x 9.75mm thick at the base. Yours will need to be around this size. If it's smaller, you can glue it in place. There is 0.1 mm clearance on all sides and the brush fits snugly and should not come out easily. The brush base is recessed by 5 mm below Z 0 to prevent accidents. v3-Straight can be placed anywhere along the sides of the bed and is designed to sit flush. v3-Corner
