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.
