Armoire Fazz Cupboard

The target was to create a cupboard from 3d printed part, MDF wood pannel and screw only !!!!
cost less of 30 €, and verry robust
There are some pictures with how to screw ;-)

Bill of material:
MDF 18 mm
screw 3.5 X 40 mm
wood dimmensions used are
top bottom and back 400 X400 mm
side 400X 375 mm
door 395X 375 mm

but a formula could be used : in my case w=400mm
top bottom and back are = w X w
side = w X (w-25mm)
door = (w-5mm) X (w-25mm)

I suppose max for w= 600 mm with
