CNC Milling Dust Shoe

thingiverse

After building a wooden CNC milling machine "Dötzchen" from CNC14.de, I've modified/optimized a few features. The most important is the dust show which helps to remove dust during milling process dramatically. The shoe itself is installed on the spindle holder and fixed with a simple clamp. As my used spindle from AMS has its fan outlet directly in the direction I'm operation the machine, I've designed a little wind fender mounted on two M2.5 brass nuts which are melted into the prepared wholes. The lamellar brush part is kept in place by magnets (2x 10mm*3mm round, 2x 5mm*2mm round) and snaped on the bottom side. The brush is available e.g. a ebay called "Flexible Leistenbürste Bürstendichtung 50 mm Faser wie Mink 6000". You need to adjust the length of the brush - I made good experience with length of ~35-40mm. Furthermore in this version you need to cut the red marked part so the brush can be pushed into the prepared guidance
