Arduino pegboard holder

I have decided to dive into the world of Arduino and to help keep my bench clear while I am programming my Uno or Adafruit Circuit Playground I made a simple little holder that fits both PCBs. Unfortunately, I misjudged the hole size I needed for the USB cable connection to the pcb and only a microUSB will fit - the porky old USB doghouse connector doesn't - but it holds the board just fine regardless.
