I'm working on a design for a 3D printed part that will fit in that cubby hole.
It'll be a pull-out drawer that fits snug inside and flush, with the ST logo on the front. I'm also thinking of making a coin-holder insert/ variation to the design.
I'll post back here later once the design is being finalized let you guys know incase anyone is interested. I'm also interested to hear other ideas for how to utilize that space.
