I made custom side panels for the Midori 5L that give 2mm of extra air gap to any fans that are close to the side. This should alleviate turbulence noise or allow for slightly taller coolers while still keeping a sleek design. This panel can be used on both sides of the Midori.

I measured the stock side panel and used that as a base for my model, then I used TinkerCAD and created the plateau which is raised by 2mm. I have not actually tested this design, because I was intending on getting it CNCed. But I failed to get a quote because it needs to be made in a real CAD program and I don't feel like learning that right now. I'm not interested in a printed version myself but maybe someone else finds this useful.
