Flexible Wire Brush Cover
thingiverse
In my maintenance toolbox, there is a small wire brush. Slightly bigger than a toothbrush, but with sharp steel (or brass) bristles. Great tool to scrub burnt plastics off a 3D-printer nozzle. Searching things in such a toolbox can be litterally painful. Sooner or later the bristles will find your fingers. Keep the bristles clean, and your hands safe. Put the brush into a prtective cover! As is, the inner size is 41mm long, 13mm wide and 21mm high. Easily scaled in cura, or if you know how to change paramters in FreeCAD: It is parametric! The entry is slightly smaller than the cavity to make sure it does not fall off. Adjust as needed. Printed with TPU standing upright, 0.2mm Layer height, 25% infill.
