This is a leverless controller mainly used for fighting games.
To assemble you'll need magnets that are 4mm in diameter and 2mm in height (4mmx2mm).
You'll also need 17 (11 on top, 3 on each side) arcade buttons of 24mm diameter and 1 of 30mm diameter.
The design is modular so you can print multiple versions of the layout and exchange them.
The author marked this model as their own original creation.
