Printer stand modeling

This was my first attempt to use Blender as real modeling tool. I built the printer stand on August, 2014.

I used default Blender unit as dimension of all objects. One unit is equal to 1 mm.
I created all objects from the plane object by applying extrusion manipulation of vertices.
And I made three clones of the leg object, three clones of the bracket object.
I didn’t made fastener objects – bolts, nuts, and washers.

Specification:
1x Plate: 230 x 350 x 13 (Width x Length x Height)
4x Leg: 20 x 35 x 400
4x Bracket: 15 x 35 x 35
