I have had some success draping plastic sheets over a wooden jig in an oven, I can imagine that to work if you want to create a small series of products. You may have to construct your product out of 2 pieces and lock those together.
Your product is functionally better than the Ikea organizer IMO since you have an extra layer of holes and the container area, though it may need a front edge, is smaller which is nice just to keep necessary things and save space on your desk as well. I would buy it. Color-wise I would opt for a matte grey base layer with top coats in an Olivetti-like pallette.
