Here are some of the replacement arcade joystick tops (and discs) that I have designed to work with your standard Sanwa type joystick, that have a screw thread.

They are push on to fit and don't require screwing.

I have tested them with a variety of different Sanwa clones and the fit varies but only a little, a first time fitting can be a little fiddly but they also don't come off easy so I see that as a good thing. Mind you don't trap your fingers between the top and your control board when the blighter suddenly drops on.

_4415H in the file name means: 4 top layers, 4 bottom layers, 15% infill & H is Hex infill.

I have designed more standard tops and intend to make more custom ones in time, please
