For the g-code for the dust shoe, I just loaded the .stl into estlcam, and pretty much let it do all the work! I used a 3/4″ piece of scrap plywood I had laying around, Set the depth limit to just over the plywood thickness, and let it rip.
Here is what I worked on tonight. Finished up the dust shoe and got it on, and then had my wife find a picture on google and I engraved it using dremel engraving bit. I put some primer down so the contrast could really be seen.
