+<h2>Overview</h2>
+  
+Scrubby is a filament dust scrubber that prevents any dust from reaching your nozzle and burning, causing partial clogs. My nozzle was clogging regularly and I 
+decided to test a dust scrubber, and I have not had another clog for a very long time, so I thought I would make this design public in case someone else can benefit.

+
+<h2>Materials needed</h2>
+  
+* 8x 6x3 Neodynium Magnets
+* Any cheap, sponge-like material (I cut up part of a scotchbrite kitchen sponge)
+* 2x Scrubby.stl
+* Note: I tested the tolerances in ABS. Due to shrinkage, other filament may make a slightly larger hole.
+
+<h2>Assembly</h2>
+
+Assembly is quite simple; press fit or super glue the magnets into each hole, carefully paying attention to polarity. Cut up your chosen spongy material and fit
+it into each scrubby half. Place your scrubby halves together, sandwiching the filament between the halves. You want enough sponge to get a nice drag on the filament
+to make sure it cleans it as best as possible. I put mine right against the bowden retainer, shown in the picture above.

+
+<h2>Notes</h2>
+
+I included the solidworks part file and the step file in case anyone wants to modify. Make sure to clean the dust it filters off somewhat regularly. It pulls a suprising
+amount off. Please message me on discord if you have any questions. Happy clog-free printing!
