This a system that allows you to position 4 to 8 buttons. Designed to be used with the MS Accessible controller, Playstation accessible controller, or hori flex.
Each of the button blocks pops out so you can rotate it to determine the button placement. With PLA you may find that the snap-in action of the modules eventually stops snapping but since gravity is on your side, this isn't an issue.
The author marked this model as their own original creation.
