This picture will show why the bottom looks wider the the top. When the top and bottom are milled the will both be the same size. The vacuum pods are made for 5/16 foam rubber gasker. I will be moving some products from a hand operation to a cnc router operation. As I do Ill be making more custom Pods meaning the height,s widths and shape will be made to fit the product. I think people like pictures so I'll be adding them as time goes on.
