Vertex Effects Riser Plate

I'm in process of updating my pedal board and am using a Vertex Effects pedal board with a riser. They don't make a plate to go into the hole in the side of the riser which is a logical place for connections. I made this blank plate to fit flush in the hole so that I can customize with the jacks that I need. 

It should just fit behind the mounting nut for the riser (you may need to twist it just a but to get it allow the plate behind it). I've included a couple of additional mounting holes at the bottom that will require a bit of modification to the riser. Figured that these might be needed when pushing cables in.
 

I've added a version with 3 d series mounting points (they mount flush when installed) and I also added a version with 3 ¼" jack openings with a space for the nut. The nut is a tight fit into the space and the threads do not protrude much with the jacks that I used.
