This is a parametric corner shelf to be printed without support as one piece.

<em>The attached STL file parameters were (all units in mm): </em>

<b>
radius=150; <em> // radius of the shelf</em>
thickness=5; <em> // thickness of the in mm </em>
previs=thickness+5; <em>// this is the front side of the shelf (let's make it a bit bigger) - default value should be OK</em>
support_l=40; <em>// length of support for screw in mm</em>
screw_d=4.2; <em>// screw hole diameter in mm</em>
support_thickness=5; <em>// thickness of the "leg" (default value is usually OK)</em>
support_width=screw_d+10; <em>// width of the "leg" (defined as screw hole + 10mm)</em>
corner_hole=10; <em>// radius of corner hole (for cables etc.)</em>
angle=90; <em>// shelf angle. Default is 90 degrees </em>
min_angle=10; <em>// minimal value for angle</em>
max_angle=180; <em> // maximum value for angle</em>
