Just working my way through assembly and fitting the side panels. I noticed that one of my panels has a slight bow. The other side fits perfectly but this one protrudes about half the thickness of the acrylic in the middle. I checked again the squaring up of the corners with the acrylic scrap and it looks good to me. I don’t really think the pillars can get any further out without going out of square. I’ve gone back over the corners and can’t really fault them. I managed to get a slight improvement to about 1/4 of the thickness showing at the greatest deflection. How did everyone else go with this?
