My DIY CO2 Laser Tube Cooler

One important part of keeping your laser working at its best is keeping the tube temperature consistent. There are dozens of methods in use around the world, everything from minimal cost low tech home brew solutions to high priced commercial chillers. With a few days off of work (finally!) and another major project on temporary hold, I had time to tackle the problem and see what I could come up with. What I came up with is semi home brew but at a very affordable price.
