[sdiy] Minimum spacing between 1/4" jacks on DOTCOM modules..

[Jean-Pierre Desrochers]

I know this could be a silly question but
I was wondering if there was any 'standard' on
minimum spacing to respect between 1/4" jacks on DOTCOM modules ??
I mean center to center spacing..
I'm building a 2U width DOTCOM audio mixer module
that could have 2 rows of 4 or 5 jacks side by side horizontaly
at the bottom...
