I decided to revisit my PDB. I have been using Brian's design for the past two years or so and decided to redesign it to be a little quicker to remove when adjustments needed to be made.

Brian's original post can be found here. https://www.cnczone.com/forums/novakon/333750-cad.html

I added an open slot so the PDB can slide on easily. It is also a little easier to make and is a little lighter than Brian's design.
