Ivan's original dust shoe didn't fit my router, thus I designed a new dust shoe using a brush. + +To not have to reprint the router bracket, I manually cut of the blocking piece from it. The STL/OBJ router bracket file in this repo is redesigned and updated, so no manual cutting should be needed. + +The brush slot at the bottom of the vaccum funnel (**P34**) was measured and the brush (**O27**) was cut at an appropriate length. The brush was then inserted into the slot. As the fit was very tight, no glue was needed. + +![dust_shoe_1](./images/build/frame/dust_shoe_1.jpg) + +![dust_shoe_2](./images/build/frame/dust_shoe_2.jpg) + +![dust_shoe_3](./images/build/frame/dust_shoe_3.jpg) + +![dust_shoe_4](./images/build/frame/dust_shoe_4.jpg) + +The vaccum funnel (**P34**) was placed next to the router bracket (**P24**) and a pen was used to indicate how much of the router bracket that was to be removed. + +![dust_shoe_5](./images/build/frame/dust_shoe_5.jpg) + +![dust_shoe_6](./images/build/frame/dust_shoe_6.jpg) + +A hand-held Fein multitool was used to remove the blocking piece from the router bracket.
