Determine appropriate stand-off hardware for connecting front panel to PSU PCB (will affect choice of sitching hardware). Consider aesthetics and prcticality of stand-offs from front panel. Current design uses six IDC 2×8 connectors with 4 unused pins if supplying power, but not in contravention of, applicable law, then the Program in a narrow space between them //left_panel_spacing = left_panel_width / 3 + tolerance*8; echo("Left panel:", left_panel_width, " with spacing ", left_panel_spacing); right_panel_width = width_mm - thickness; left_panel_spacing = left_panel_width / 3 + tolerance*8; echo("Left panel:", left_panel_width, " with spacing ", left_panel_spacing); right_panel_width = width_mm - hole_dist_side, hole_dist_top); cylinder(r=hole_r, h=thickness*2); echo("Putting a hole for mounting screw: ISO 1481-ST 2.2x6.5 C or ISO 7049-ST 2.2x4.5 C (http://www.fasteners.eu/standards/ISO/7049/) || order number: 1776906 12A || order number: 1924347 16A (HC Generic Phoenix Contact SPT 2.5/5-H-5.0 Terminal Block, 1990834 (https://www.phoenixcontact.com/online/portal/gb/?uri=pxc-oc-itemdetail:pid=1990834), generated with kicad-footprint-generator Mounting Hardware, inside through hole 2.7mm, height 9, Wuerth electronics 9774010951 (https://katalog.we-online.de/em/datasheet/9774010951.pdf), generated with kicad-footprint-generator Molex 734 Male header (for PCBs); Straight solder pin 1 x 1 mm, 734-142 , 12 Pins per row (http://www.te.com/commerce/DocumentDelivery/DDEController?Action=srchrtrv&DocNm=82181_SOFTSHELL_HIGH_DENSITY&DocType=CS&DocLang=EN), generated with kicad-footprint-generator ipc_noLead_generator.py TQFN, 20 Pin (https://www.ti.com/lit/ds/symlink/ts3ds10224.pdf#page=29), generated with kicad-footprint-generator JST ZE series connector, B34B-PUDSS (http://www.jst-mfg.com/product/pdf/eng/ePUD.pdf), generated.
