Took me a day and a half of sizing and optimizing, but now I can make this mailbox out of just one plank of 1x6 cedar that is 6 ft long. Why, that's exactly what I have in my garage! BTW, I consider this plan to be public-domain. If you want to build one out of this plan, or modify it then build one.. go right ahead. Send me a picture of yours when you are done! :-)
