$30 Adjustable Shelf Display Case

This pretty cool looking display case was a really awesome build. It took me and my Papa a weekend to put it together, probably 4-5 hours in the garage. It is a pretty simple design, all it is is basically shelves suspended on a 3' long screw with nuts and homemade washers made out of a strip of aluminum. Though the though didn't cross my mind after like through the isles of lowes for an hour or so. I am hoping on completing it by sand the edges cause they look pretty rough. Then putting some felt on the selves so that I can display my old electron tube collection (last pic). Please vote for me and leave a comment!
