Most of the enclosure and the buttons is 3D printable. If you own a 3D printer, you can print it yourself. The only not 3D printable part is the plexiglas pane. It comes with the kit and brings a professional design out of the box. To ensure a classy look, the encoder knobs are professional aluminum caps and the fader cap is a standard audio product, used in professional mixers. Both parts come with the kits.
3D models to print it yourself are Open-Source, too and can be downloaded from the GitHub project.
