This is just a very simple 2 layer rectangle. My Anycubic Kobra Neo sometimes dribbles filament before a print or has a little booger on the nozzle. I needed a stick to get that off as the nozzle hits temp. I print these in batches of 6, they are meant to be disposable. You could also use them for an adhesion test or a first layer test I suppose. Do what you want with it.
