Stand And canopy design

[SeaSerpant]

Okay i am going to get a 60g aquarium soon so then i'll have 50g FW and a 60G SW on the same stand. I have drawn up the stand but i don't know how to make a canopy. I have used only my 50g dimensions because i don't know the 60g dimensions. Edmonton Eskimo this is for you.

The first picture is of the stand bone and the second is with the skin on (the bones of it you can't see because i didn't put them in in the second pic)
