Simple storage for all the threaded rods, bars, dowels, and misc long-thin items I use for models/modeling. The base and middle "support" are printed, along with a lifting disc for each tube. The tubes are just old-school fluorescent T12 tube guards, cut to length as needed. To make the lifting disc, I added an appropriate length of aluminum welding filler rod and hand bent a loop at the top for easy finger access.
