Slimbox Deep Base tray - Hitbox

Building on the great work of @Alpenmeister_111725 elsewhere, I needed some more space in my hitbox for pico I had with headers already soldered on. It also gives it a slightly more chunky look, and a bolder base colour which you may or may not like. Original slimbox is…slimmer… and has a flat base piece. This just makes it a bit thicc-er while note getting to far away from being slim. Longer screws will be required.
