I have two racks I made out of 2x4 and another 1x2 , they hold hardshell guitar or bass cases like a bookshelf , or soft cases. I was able to fit about 7-8 bass guitar hardcases on each one depending on thickness. They are about 30 wide 17 deep 30 tall will post exact measurements. The one with 1x2 is lighter and comes apart by decking wood screws. The 2x4 is put together with a nail gun and won’t come apart unless you destroyed it. They are both covered with primer and thick coats of spray paint. I also put foam to pad the spots where cases rest. I’m asking 50$ each.
