Hey if you are going to make this again with acrylic I highly suggest making a rib on the long piece of acrylic by welding a piece maybe 1/2 inch wide vertically to the center of the long piece so it looks like a really wide upside down T. This will increase the strength of the acrylic greatly. As it is now it will slowly sag more and more. This is just opinion from someone who has made many many prototypes from acrylic. The other way to fix it would be to use thicker acrylic on the top but then you are adding more weight which may cause more sagging.
