I decided to try my hand at making my own.
Here is the router maiking the part that will attache to the festool mounting posts. You can also see my second gen dust shield. This one has a little piece that lets me access the router bit for setting Z axis with my probe.

Now here is me insering the pen into the holder and drawing some text. I had the thing set to feed abit too fast but it still came out well.
