Here is the board assembled and adhered to the skate frame.The battery pack lives in the gap between most boots mount points. I forgot to add thermal reliefs to the ground pads for the LED strips when I changed the layout of the board. I was also impatient and adhered the PCB to the frame with some thermal tape. So I had a hard time soldering the ground pads... hopefully there aren't any major cold solder joints that will break when I subject this to vibrations on the asphalt.

Fortunately everything else is still working. It remains low profile. So now I just need to 3D print a translucent cover to act as a light diffuser and dust/debris protection. I'll eventually add a conformal coating, but I expect to need to make changes as I test this.
