So far so good…
In the next step I extracted the shapes of main component boards to know how much material I need. Material is MFB 18 mm thick (in pieces 2x1 m), raw surfaced, so it needed later at least two layers of fast drying varnish. Side panels, front panel and front cover board is black coated 18 mm MFB (the most right board in picture). SketchUp file
