I don’t think 45 degrees is necessary. You’d have to move the hinges closer to the center of the table, otherwise your legs will stick out on either end. I like the look of the table now, I’m trying to not change it too much.
I also changed the security settings on the website, so everyone is able to upload Sketchup files now! You can just drag and drop the file into the editor box, like you do with pictures, and everyone else will be able to download them.
