Sand all the pieces. I only have a mini CNC machine, so it took a while to cut out and the edges were pretty rough. I started with 120 grit and finished with 220 grit. I then used a 1/8 inch round over bit on the router to break all the edges. Then used a 1/4 inch round over on the inner brush holder. This fit the contoured handle of the brush nicely. I also used the table saw to cut the notch in the post. I used a drill press to make the holes in the post, but a regular drill would do just as well. I used 3/8 inch diameter dowels, but you can use whatever you have, just make sure you adjust them in the base and top as well.
