I had a similar issue when I glued the first one up, after I had it clamped I realized I had the baffle upside down, fortunately I was able to pull the brace and bottom off and reverse.
I had a change in plans. I was initially going to run the large side down to the floor, with the side doubled up below the bottom. I cut the sides and temped it up but I didn't like the way it looked so I decided to build it as designed and build a separate stand for it, I am still working on the stand design.
A couple of minor changes to the base and the brace, here they are so far:






Paint can for scale, to me they appear larger in pictures that they actually look.
I was considering a wrap for this but I think I am going to give painting a shot.
