I've had an idea of designing a cup that would slide into the hole and could be pulled out to store stuff. My idea is that the cup would fit tightly into the space and sit flush with the face, but would have a hole/knob/lip that you could slide it out. This could be useful for storing change and other small loose items. I'd add the ST emblem on the outside either inset into the face or embossed on the outside in red (custom colors may be an option). This way, you can cover that ugly hole AND make it functional!
I do some 3d modeling and printing for fun and have been looking for fun and useful things to make for my FiST. If people seem interested in this, I may go ahead and start designing it soon. Here's an example of something I've recently finished designing. It's a removable cup for inside the center console that fits flush and makes it easy to remove loose change and other small items.
Let me know what you guys think.
