Test Resistor Box

I needed to mount some precision axial resistors for test/calibration purposes. I decided to use 4mm Banana jacks that I ordered from Amazon. First problem was to derive accurate dimensions for the Banana Jacks. Next I did a layout (2D) for the mounting panel and a box to hold it. It is designed such that one can use the Banana jacks or flip the panel over to access the resistors directly.
