Had two quick questions for you. The video building the side sills that mount on the sidewalls, you had stacked 3 boards. Is the thickness 18mm or 12mm? I'm going to start my sidewalls in the next two weekends and planning my cuts out on my CNC.
Second question is backlighting. What are you using for backlighting for the MIP. I was looking at this from Amazon: https://amzn.to/36wXqIS. What are your thoughts?
