The Qanba N1 arcade stick comes with a circular restrictor plate so I designed an octagon and square gate since I prefer those. The Qanba N1 uses a joystick that is similar to the Sanwa JLW so this might work for it as well.
** The newer version have a round shape to save on material and also the square gate will have more holes so you can use it as an 8way or 4way restrictor.
It takes about 30mins to print at 0.20 layer height with ABS filament.
