This combination is: (apart from some minor details)
-affordable (although no indication of 3d printed part)
-all available parts

For 3D printing maybe Shapeways could provide any help? It is also based in Eindhoven, so shipping costs may be low.

For the design you now have, is there any possibility to make holes for the cam and flash, since the keyboard has some room left?
