@vholfx - my bad, I completely forgot about this, apologies.
I've got this done tonight. I've made a version with the universal stud pattern of mine, if you need a version with the stud positions for the E3018350A joystick bracket then let me know and I can make that too.
Download link is in the OP but I've also copied it [here] too for convenience.
A friend of mine told me he was making some 1P Mortal Kombat fight sticks so I offered to make him a drilling template to help him drill the button holes as well as the holes for the IL Eurojoysticks he is using:
Mortal_Kombat_IL_Drilling_Jig.dxf
I managed to find the dimensions for the buttons positions from [this] web page which just so happen turned out to be @twistedsymphony 's Thank you!
Whilst drawing up the panel above I thought I might as well draw up the main MK3 and KI2 layouts that he had drawn and export them as .dxfs in case they are useful to anyone in the future. I saved an additional version of the MK layout but without the run buttons.
Mortal_Kombat_1_2_Control_Panel.dxf
Mortal_Kombat_3_Control_Panel.dxf
Killer Instinct_2_Control_Panel.dxf
They can be downloaded in the root of this folder in my gdrive [here].
Credit to @twistedsymphony for measuring up his control panels and sharing the dimensions.
