In my projects I use a variety of wire colors and guages. I usually have several projects going at one time, so and I needed a portable way to bring the wires to the projects. I took a cheap plastic box from a big box store and cut some holes in the ends. I cut some ¼ inch threaded rod to size, added the wire reels to the rod and bolted the whole thing together.
For one last improvement I used an old solidering iron to melt a hole in the front for each of the 26 guage reels. I threaded the wires through the holes and now I have a simple and effective wire dispenser.
The 26 AWG reels of wire are from Pololu.
Somethings the simplest way is the best way. Now go build someting.
