Sure thing, you should be able to download it here
I didn't put all of the details in the model, such as doors, top, electrical etc. I mainly just wanted to get a better plan on how to frame it. I framed each section independently like the image below shows.
Some of the dimensions I used were based on where I was going to be keeping it. For example I used 4x6 on the bottom and gave it that lip so it would fit closer to the wall in garage. I used the chosen depth to make sure I could still fit 2 cars in the garage.
I also didn't originally plan on putting casters on it. Once I started putting it together I realized that even empty it was going to be tough to move it without them. With the casters added it barely cleared my garage door. If I were to do it over I would probably use 2x4's for the base and maybe even shorten each section by a few inches.
I took a lot of time to ensure the chamber would last a long time. I've read about a lot of people who build something like this and end up throwing it out after a few years due to mold or other problems. The frame on this is definitely sound, my biggest concern was moisture. Between how well I sealed everything up and the moisture absorber I don't think I will have any problems. I also made sure the A/C unit could easily be removed and replaced if needed. This thing should be chilling for many years to come
