Tenlog Hands 2 Nozzle Swipes

thingiverse

Wire brushes can be inserted into these holders to prevent unwanted oozing while using the dual extrusion on the Tenlog Hands 2. If a filament emerges from an extruder in the park position, it is wiped off by the brush when the extruder moves into the printing area. As a brush I used a commercially available wire brush to clean spark plugs (as seen in the picture). This must then be sawn into suitable pieces of 15x14x10mm and inserted into the holder. The brushes then hold on their own, so they do not have to be glued and can simply be replaced when they are worn out. Depending on the brush, the bristles must be shortened to the appropriate length. The brackets can be attached with two M3x10 screws on each side. The holders come in two Versions, labeled "L" for the left and "R" for the right side. UPDATE: I uploaded a new version called "_Hole" in the filenames. These models are a few millimeters longer a have a hole right underneath the nozzle, so that extruded filament can go throu. This will make it easier to load or unload filament.
