rectangular bar 3d model

Create one single solid hard-surface CAD object. A straight rectangular bar with proportions 150 x 40 x 36 mm. Chamfer all four long longitudinal edges equally, creating an 8-sided cross section. Constant cross section along the entire 150 mm length. Both ends are flat and perpendicular to the length. Perfectly straight, symmetrical and simple. NO gaps, NO slots, NO layers, NO seams, NO separate parts, NO openings, NO taper, NO curvature, NO protrusions, NO decorations, NO texture. One continuous solid object only. Clean flat planar faces and sharp geometric edges.
