CNC cut 1/2" Baltic Birch. It works great. Easy to mount using two screws. It also has a little pocket to store nozzles and those troublesome red spray tubes that are always getting lost. Dimensions are 17.5" tall, 28" wide, 5" deep. Holds 24 standard 2-5/8" spray cans. Can holes are 2.73" dia.
Comes un-finished and unassembled so you can varnish it, paint it, or use it as-is like I do. The only tool required for assembly is a rubber mallet or something similar.
