DIY Stackable Water Bottle Storage Rack

Decide how long your water bottle organizer will be and cut the three 1x2 rails to that length minus 1-1/2". Cut two 1x6 end panels at 8" long. Sand any rough cut edges.

Screw or nail the 1x6 end panels to the 1x2 rails. One screw per joint is enough if screwing; if nailing, use glue and two nails per joint. The outer 1x2 rails stand vertically as side walls; the center 1x2 lies flat.

If building multiple racks to stack, use mounting tape to hold them together.
