So, I bought this bright orange silicone case, and instead of doing something simple, I decided to torture test the F2 Ultra UV. 😈
I went straight to the xTool Studio library and picked the very complex, line-heavy heart mandala I could find. My thought process: "If this machine really is a 'cold light' monster, let's see if it can handle high-density lines without turning this rubber case into a sticky, melted mess."

The "Lazy" Setup (That Worked): xTool Studio didn't have an "Orange Case" preset at this moment. Did I overthink it? Nope. I just selected "Pink Silicone," loaded the default parameters, and hit go. Since the F2 Ultra UV doesn't rely on heat/burning like a diode laser, the color difference didn't matter at all.
⚠️ A Quick Note on the Mess: If you see my process photos, the design looks super gray and dusty. That's because I kept the lid OPEN to film a video (don't be like me—close the lid and turn on your purifier!). Silicone engraving creates a fine white powder. It looks scary at first, but the second I wiped it with a damp cloth? BOOM. 💥

Perfect, crisp lines. Zero yellowing. No melted edges. The detail on this thing is actually insane.
