Spool Shelf Bracket

Yet another spool shelf bracket design. Intended for small electrical conduit which is about 0.7" (18mm) OD, and max 200mm OD spools. The end caps are in case you want to safely put spools beyond the last bracket; they use 2-56 x 1/2" screws and keep spools from sliding off. You'll probably need to drill (to clean) and tap those holes.
