This is something I've done for quite a while now. Buy a one spot daisy chain and you can cut it up into pieces, the first has the female end on it and will plug right on to a PP2 cable making it longer. You can leave part of it together like two outlets long for a daisy chain if you need power for an extra pedal. The rest of the One Spot can be simply cut up into male to male cables with 90 degree ends. I snip them apart with a small side cutter and then use a staight pin to be sure non of the wires are shorted out. Finally I test them for short/conductivity with an ohm meter. Cheap and easy.
