After a highly exhaustive process, I have finally completed my template panel for my lamp on CAD. This involved me drawing a 1:1 scale drawing of one of the panels, then measuring every point - some 200 co-ordinates.

I then drew lines to those co-ordinates in CAD from an origin so that I could firstly create an initial curve for the holes to follow, then I created boxes forming rough markers for the holes, then created arcs for the rounded corners of each of the 48 holes, then joined them up with uniquely curved lines.

At this stage, I haven't been able to determine why I'm unable to compress the shape to make it narrower for the longest panel. I have managed to scale them properly, but only the long panel is hampering my efforts, so all that remains is the 2 long panels and the base of the lamp to complete. The base, however, will require me to attain an actual light fixture so that I may acquire the appropriate measurements. All in all, I'm quite satisfied with the way these panels are looking given my lack of experience creating these complex shapes on a computer.
