Second build of 2020, and also second build on this style of box. I started doing a locking bracing system, where all braces are locked under another structure. This makes sure that even if a brace comes lose, it will not compromise the support system. The last brace goes over the X brace at the top, and slides slightly from left to right so it can pin everything else in place when it is glued up. Lots more time, but really satisfying build. This one I am keeping for my daughter.
