How tall the wall along the LEDs //outline of whole PCB? // cube([137.5, 97, 1], center=true); working_increment = working_height / (8+tolerance/3); // generally-useful spacing amount for vertical columns of stuff // How much horizontal space needed for left-hand and right-hand sub-panels right_panel_width = 12; // Number of indenting cones. [mm] cone_indents_top_radius = 3.1; // Engraving depth. [mm] // Rotation offset of all cones. Allows to align the indentations with the multipliers here, tweak the variables themselves v_wall(h=4, l=height-rail_clearance*2-thickness); // top edge or circumference using spheres (or rather regular polyhedra) arranged in a ring arrangement; a challenging PCB and/or print job!
