List of parts for a from scratch diy 3d printer

[Marcell]

Hello. I would like to get suggestions for a part's lists in order to build a cartesian printer having the following specifics:
400x400x400 bed (or 500x500x500, if related parts exist), 10mm belts, 8mm threads & shafts, filament check, wifi capability, bed leveling probe, job resume, color display, led lights to illuminate the printing area, dual extrusion, direct drive (preferably slim nema17, or normal nema 14).
The frame will be in aluminium (I have anyway the capability to works thin metal sheets): some parts could also be printed by my current 3dp.
Price is not an issue: obviously, the lower the better.
Thanks for your time.
