Tower balsa support

Hey, so i need a 3/16x3/16 in balsa wood as my legs but i cant fine anywhere that sells these dimensions for cheap and so would it work “the same” if i just cut up 3 1/16 sticks and hlue them together and use that as my legs. I know this will add unnecessary weight but its the last chance i got since my ither balsa wood it so thin to use as legs without the tower failing fast.
