Power block (for multiple fans)

I created power block design for fans to be connected, but it can be use for other low power devices and 5v too.

I use a simple board like veroboard rather than hard wired. pairs of wire for the input and up to 5 devices. You can leave the wires out and plug in and still have four outputs.

the block comes in two parts, one black stripe for 0v or gnd. and the other stripe is red for +V, either 5v or 12v or any other volts. you can use yellow as indicate as 12v (red for 5v). Your choice is endless. Last thing you can hot glue it together or superglue.
