Modular Synth Panels

Hi,

  I've been trying to come up with a design for the Buchla 281 clone
project available at e-music.com but am not so good at making panel
designs.

Does anybody have a design they'd like to share :)  My biggest worry
is getting the pots spacing correct so I can use the PCB mounted pots.
 Any format will do as I can cut and paste to my taste.

Thanks,
Dave
