Shelf Bracket for American Lighting Color Changing Neon Flex Light

I bought an American Lighting Color Changing Neon Flex Light kit from Costco and wanted to put it up against some shelves I have on my wall.  The kits comes with 10 brackets and I wanted more so I designed this OpenSCAD file that allowed me to play with the dimensions until I had something that worked for my ¾" or ~20mm shelves.

I found that a brim helps keep the file on the plate during printing and comes off pretty easy.
