@Whiterose0818 I am not sure if this helps you at all but here is some info quoted from VU:
Here are the files I made: https://www.dropbox.com/sh/y3zbf45n99x4538/AADwpeoQMlE-EdZvFOAGw9Nwa?dl=0
The enclosure I used was an Alpinetech CNC 1590B. There is a PDF printable template. The board holder was 3D printed from Shapeways, you can use the STL file to do that (it is in millimeters). The dual 20700 tray is IM2X20700 from MosMax Electronics.
