Needed a way to wall mount my spray paint collection that also let me read the labels. Tried a few options that stacked cans but could not get a clear view of the labels which led to rummaging around which was why I wanted to rack them in the first place.

This design uses 1x1x1/16" aluminum extrusion and holds cans up to 3" wide which covered every weird can that I have. I used 48" lengths of extrusion and there is minimal sag when fully loaded and the brackets seem to be holding up well. Also can fit caulk and sealant tubes without them slipping threw the gap.

Printed in PETG for durability and temp resistance since mine is mounted in a garage.
