I recently picked up a Punk Workshop Silicone Rubber joystick (https://pws.top/products/pws-joystick-1?VariantsId=11268), and it has some unique requirements for a mounting plate (details on the wiki (https://gamesx.com/wiki/doku.php?id=arcade:joystick_mechs#punk_workshop)). It comes with a plate that's compatible with newer panels, but it doesn't fit the old Sega v1 mount (https://gamesx.com/wiki/doku.php?id=arcade:joystick_mounts#sega_aero_astro_city_v1_panel_mount) seen on the Astro City and similar cabs.

So I made one.
The top of the round part of the mechanism is about flush with the top of the plate, so its depth in the panel is the same as a Sanwa or Seimitsu stick.

I print it with the large central part on the print bed, using supports for the wings. You could print it on its side as well, but I leave the specifics to you, oh exalted reader.
