Improved stability of the dust shield

I use this dust shield for a long time and it does its job pretty well. However, the original idea to stick it to the cover does not fix it forever and the sticky tape I used wasn't really functional any more. Of course I could replace the tape but I found that sometimes when I pressed the cover in position the dust shield did not find its position so I quickly designed these elements and glued it to the dust shield with super glue so it literally "rides" on the black guide rail next to the saw blade. Then no sticky tape is necessary on top. Just press the cover on the positioned shield and it works! The rectangular piece is just to reinforce the joint where the two parts of the original dust shield are glued together. It is not necessarily needed.
