Yes... I have details on how in my garage... Simply used cardboard for template. Transferred template to plywood. Used clear vinyl we use here at my work for insert.
Version 2.0 will be better fitting 2 ply that will sandwich the clear vinyl. If vinyl becomes blurry simply remove 4 screws, 1 from each corner and replace. I will need to cut four frames for this two for each side. I will then roll on herculiner to all panels so that they will last longer.
