From the beginning I designed the USB Tester to use the Dangerous Prototype Sick of Beige (SOB) standard PCB sizes. 50x31mm being the smallest rectangle and most ideal for the USB Tester. One of these reasons was that in doing so it would fit their standard acrylic cases which can be found at Seeedstudio.com for $3. After waiting many days, my order has come in and I can show you one way you can use the case.
When you order the enclosure it comes with the following:
- 4x Long Screws
- 4x Short Screws
- 4x Tall Stand offs
- 4x Short Stand offs
- 2x 50x31mm Acrylic cut with mounting holes
I found what worked is to use one acrylic sheet, all eight hex stand offs and the four long screws.
Start by putting the longer screw through each of the corners and then thread the longer of the hex nuts.

Now you can put the USB Tester on top and then the shorter hex nuts to tighten it down.

If you have the OLED Backpack you can attach it now.

The great thing with the Sick of Beige base is that it adds a bit of weight and when using a DMM, it keeps the leads from going too far into the holes and touching each other. Not to mention touching anything else on your workbench.
