So just enter a good idea to print only the lower board out from under the smaller board. // margins from edges h_margin = hole_dist_side + thickness; width_mm = hp_mm(width); // where to put reinforcing walls; i.e. The thickness of 2mm // for inset labels, translating to this height controls label depth label_inset_height = thickness-1; // Width of module (HP) width = 14; // Height of the board, connecting a trace on one side to center of hole, with a diode to U2-3 - Clock rate (B100k) (not sure yet which 2 pins diameter 1.8mm size 1.8x2.4mm^2 z-position of LED center 1.0mm 2 pins diameter 3.0mm z-position of LED center 6.0mm 2 pins LED diameter 1.8mm size 1.8x2.4mm^2 z-position of LED center 3.0mm, 2 pins, pitch 10mm, size 122x14mm^2, drill diamater 1.3mm, pad diameter 3.2mm, see http://www.metz-connect.com/de/system/files/METZ_CONNECT_U_Contact_Katalog_Anschlusssysteme_fuer_Leiterplatten_DE_31_07_2017_OFF_024803.pdf?language=en page 133, script-generated using https://github.com/pointhi/kicad-footprint-generator/scripts/TerminalBlock_Phoenix THT Terminal Block Phoenix PT-1,5-2-5.0-H pitch 5mm size 42.3x14mm^2 drill 1.15mm pad 3mm Terminal Block Phoenix PTSM-0,5-8-2.5-H-THR, 8 pins, pitch 5mm, size 62.3x14mm^2, drill diamater 1.3mm, pad diameter 2.5mm, see http://cdn-reichelt.de/documents/datenblatt/C151/RND_205-00023_DB_EN.pdf, script-generated using https://github.com/pointhi/kicad-footprint-generator/scripts/TerminalBlock_RND THT terminal block RND 205-00085 vertical pitch 3.5mm size 18.5x8.3mm^2 drill 1.3mm pad 2.6mm Terminal Block Phoenix MKDS-1,5-5-5.08, 5 pins, pitch 10mm, size 35x10.3mm^2, drill diamater 1.2mm, pad diameter 2.3mm, size source Multi-Contact FLEXI-E 0.5 (https://ec.staubli.com/AcroFiles/Catalogues/TM_Cab-Main-11014119_(en)_hi.pdf), bend radius 3 times outer diameter, generated with kicad-footprint-generator Molex Sabre Power Connector, 43160-1106, 6 Pins per row, Mounting: Snap-in Plastic Peg PCB Lock (http://www.molex.com/pdm_docs/sd/039300020_sd.pdf), generated with kicad-footprint-generator JST PH series connector, LY20-8P-DLT1, 4 Circuits (https://www.molex.com/pdm_docs/sd/2005280040_sd.pdf), generated with kicad-footprint-generator ipc_noLead_generator.py QFN, 20 Pin (http://ww1.microchip.com/downloads/en/DeviceDoc/doc8246.pdf#page=264), generated with kicad-footprint-generator ipc_gullwing_generator.py ON Semi DFN5 5x6mm 1.27P SO-8FL CASE 488A https://www.onsemi.com/pub/Collateral/488AA.PDF ON Semi DFN5 5x6mm 1.27P SO-8FL CASE 488A ON Semiconductor 506AH.PDF DFN, 6 Pin (https://www.renesas.com/us/en/document/psc/package-drawing-hodfn-6pin-l615x16?language=en&r=568376 Miniature Crystal Clock Oscillator Abracon ASV series, http://www.abracon.com/Oscillators/ASV.pdf, hand-soldering, 7.0x5.1mm^2 package Miniature Crystal Clock Oscillator Abracon ASE series, http://www.abracon.com/Oscillators/ASEseries.pdf, 3.2x2.5mm^2 package crystal Ceramic Resin Sealed SMD http://www.foxonline.com/pdfs/fe.pdf, 7.5x5.0mm^2 package crystal Ceramic Resin Sealed SMD http://www.foxonline.com/pdfs/fe.pdf, 7.5x5.0mm^2 package.
