Bracket to Re-purpose Shoe Rack to Plant Trellis

I had one of those simple wooden shoe racks hanging around, like in the 3rd picture, and decided to convert it to a wall mounted trellis for my climbing plant.

The actual 3D printed part is a simple custom bracket to hold the shoe rack close to the wall. The part of the bracket where the wooden rack sits is 19mm wide. I've included the SketchUp file (.skp) if you wish to modify it.
