PCB sandwich, making some final-ish decisions about connecting to front panel candidates v1 and v2

Added schmancy pcb for v2 front panel design and includes 2.5mm centerward shift for input and output jacks working_height = height - v_margin - title_font_size*2; saw_out = [output_column, bottom_row, 0]; c_tune = [width_mm/2, top_row, 0]; left_rib_x = thickness * 1.2; right_rib_x = width_mm - right_rib_thickness; // projection: make a hole with radius: ", hole_r , " at ", width_mm - col_right + tolerance*4 + 8; //three knobs plus space between them right_panel_width = 12; // [1:1:84] // margins from edges h_margin = hole_dist_side + thickness; working_height = height - v_margin - title_font_size*1.5; saw_out = [third_col, third_row, 0]; //Fourth row interface placement pwm_in = [first_col, fourth_row, 0]; //Fifth row interface placement triangle_out = [third_col, fifth_row, 0]; square_out = [width_mm-h_margin, row_1, 0]; right_rib_x = width_mm - thickness*2; // draw panel, subtract holes // label the whole part.
