i used one continuous oak board (easy cuts) to make this: 

lots of sanding, some stain, etc.  I used the scraps to create supports for the bottom side (given the stomping): 

i used a 1 3/8" hole saw to cut an opening for wires.  i then took that plug and split it in half to make posts, to wrap the excess wire:

on the underside, i used wire ties, tacked into the wood, to secure the power lines:  

in the far corner above, you can see i velcroed the transformer onto the underside.  then, velcro on the top, and on the pedals, and a $6 leather handle:

then, rubber feet on the bottom, and wire it all together.  PS this is not representative of my pedal setup, this is just for testing!  i'll post the actual rig soon.  

it's made it through 6 gigs.  hopefully more to come (we have about a dozen lined up!).

what i'd change- it doesnt stand on it's side, probably because of how heavy pedals are.  to put a stand plate on one side would mess with the aesthetic.

what i'm thinking of adding- maybe a shoulder strap so i can make one trip from the car to the studio. 

i can send plans if anyone wants.
