navs.modular.lab where you'll find another pic and sample. Note the faceplate only is Make Noise:
"I used the DIY Layout Creator to plan my perfboard and a 6HP Makenoise blank as faceplate. This was the first time I'd made a parallel board, which meant using wire connections for the jacks etc. However, the benefit of this was I didn't have to be totally accurate when drilling holes. "
