Go to a hardware store and buy a set of tin snips, (or a left and right hand tin snips if you are feeling spendy) and a good pair of pliers with flat and wide grip teeth. With the measurements from the above images you can draw an "unfolded" sketch of the burner as if it were a flat plate. Then you can try cutting that shape out of an aluminum can or tin can. With the pliers you can fold the metal right up to make a perfect little tray. Might not look perfect, but if the point is functionality it will do that. You can also buy brass and aluminum sheet at the hardware stores that will make things turn out even better, but I had to make a few out of tin cans before I wanted to spend the money on a metal sheet. (hardware stores charge a loooot for metal sheet) https://a.co/d/8u4mcrq

When you price out tools for a simple job like this it seems like it isn't worth it, but I have been finding any tool that's value is even partially offset by money not spent on a commercial product, is worth building the skill and buying the tool. Like I made 3 or 4 of these fuel trays, and years later I have bought a house and use those same tools and skills for my ducts more than I wish I did haha! Sorry this is probably coming across as condescending, but buy the tools and make one, the Microcosm tray is not the right size, I can measure mine if you realllllly want me to, but it is a very different form factor.
