I have just brought some Adafruit SNES connectors for my RetroPie project. On Adafruit’s website it has the dimensions for the connector but no suggestion if this is the cutout size or overall size. Also from the images it looks like there are ‘key’ notches on the side.
Having now had it in my hands I have measured it out and made up a DXF file which has the panel cutout and overall size including the key’s.

Hope this is of help to anyone wanting to use them in their own projects :D
