I've really liked hitbox controllers for Street Fighter 6. I've been really happy with how they've turned out and they're a joy to use. If there's interest I can post the build process/instructions/guide.
Thanks. Made the cases from scratch with wood and covered them in vinyl wrap. On the controller with 8 action buttons I used the lid of a wooden box but then had to carve out spaces for connectors and make the base by hand.
My primary aim was to make the size as small as possible with full size arcade buttons.
But wait, there's more. . I usually play on the Steam Deck (which only has one USB port) and this way I can plug a charger or second controller into the side of my hitbox, or even wired headphones.
