Pedal box?

[happyjo]

Can you guys help?

I remember reading a thread on here about making the pedal box and CP16 out of one complete sheet of 3mm

Looking at the drawings it shows CP16 (1mm) as being 277 width and 210 Height.

Pedal box 284mm width (which does include the 16mm section angled at 20 degrees and height as 150mm.

My question is if I made the plate 284mm wide, how tall would it be in one piece?.

I cant add 210mm and 150mm together because they overlap.
