For supercon I populated 4 of these boards that I made for the Supercon Add-on contest, but didn't publish before bringing them to Pasadena. These 10 packs of the trucks reduce the BOM considerably! There's probably something you can do with the UV PCB stuff, basically print your favorite deck in small and then add trucks to it.
