I will watch your project. Liked the concept.
Just: 4040? Ok, 2020 is, for sure, too weak, but 4040 looks like is stronger than you really will need and the cost will increase also.
I also like the idea of bigger bed instead of the regular 200x200 but for sure I will like more the 300x300 then 400x400 (superb big) or 400x300 (not regular).
