Densha De Go Arcade Mascon Detent

I noticed that the Mascon on my Densha De Go arcade cabinet sometimes stuck in the accelerate position. When I took it apart I found wear on the detent causing binding. The quickest fix was to flip the detent 180 degrees, but I wanted to make a 3D model of the parts before they wore any further. This part probably cannot be 3D printed, it should really be milled out of UHMW polyethylene. You could maybe try pure PA6 nylon on a consumer 3D printer, but I don't know if it would be low enough friction. This part has been dimensional tested with PETG (but the part itself was non-functional, due to being too high friction).
