I bought two 10 ft lengths of 1" sch 40 PVC, ten 1" end caps, ten 1" 90° corner elbows, and a handy pack of Oatey primer & glue for about $30.00.
I cut ten 12" pieces and five 14" pieces.

I primed & glued them all together. The 12" pieces are the vertical pieces of pipe between the end cap and corner elbows. The 14" pieces are the horizontal pieces of pipe between the two corner elbows.
