I apologize, This is a bit of a repost, my old post I was in the wrong section, and got a bit derailed and wasnt quite clear in what I was asking, so Im attempting to start over, and ask this a new way, correct way and in the right section

Im ready to send in a custom control panel order to mameroom. However I have to use the Control panel maker program they provide, and properly layout the top holes before doing so.
Here is what I have currently. (ignore the wierd button on the bottom left. I can't seem to get rid of it, it's not supposed to be there.)

After tons of research and bad attempts, I cant get everything to line up properly.
My main issue is that im over thinking it because I want this part to be perfect.
Im just looking for some advice on how to properly space out the buttons, from Each other, from the top/sides, and so that they are comfortable and correct.
I have them layed out basically how I want them, with the buttons in an arch, trackball in the middle.... from here I just need them to be lined up, and even and spaced correctly.
If anyone could help me figure this out, Id greatly appritiate it
