Positioning panel

A positioning panel for fixing items, which contains a top surface (front) and a bottom surface (base) with a number of multifaceted through-holes in a panel body;

• opposite facets of multifaceted through-holes are equal, and multifaceted through-holes are arranged in rows in the panel body;
• there are chamfers on the top and bottom surfaces of the panel at a location of multifaceted through-holes, differs in that a number of facets n is multiple of four, but more than eight, and adjacent facets have different width, and a chamfer slope angle, i.e. an angle between the plane perpendicular to the top and bottom surfaces of the panel, and a chamfer plane, is within (20-50°), and a facet slope angle, i.e. an angle between a plane perpendicular to the top and bottom surfaces of the panel, and a plane of the multifaceted through-hole facet, is within (0.1-4°);
• and an inner surface of the multifaceted through-holes narrows towards the base;
• and the panel contains conical through-holes smaller than the multifaceted through-holes;
• and the multifaceted through-holes alternate with the smaller conical through-holes, subject to a condition of 2≤S≤14 mm, where S is a minimum distance between the multifaceted through-holes, measured along the top front surface of the panel.
