Industrial Design Preliminary 1

I have completed my first Preliminary Industrial Design and am ready to create my second!! I have to fix where the top joints connect to the top plate and make them 1/8" longer, so they do not create a gap in between the joints and the table top. I am also going to round the top board edges off, instead of having them stay as a sharp edge. I will also make the cut - out a 1/4" deep instead of an 1/8". Finally, I will get some glass to put into the 7" square cut - outs. I am envisioning a sort of wavy glass that could flow with the grain of the wood, but I am open to suggestions.
