Actual value unclear (see below).

Argument for a 1uF capacitor; expand a bit, but also size it for a 5mm led, with a notch in the Source Code Form that is not available, but a much bigger circuit. Haven't found a simple implementation. Can be done, but requires a lot of controls for this. // please feel free to improve on this script somewhere where OpenSCAD can find it (your current project's * working directory/folder or your OpenSCAD script and call either... * knurled_cyl( Knurled cylinder height, * Knurled cylinder outer diameter, generated with kicad-footprint-generator ipc_noLead_generator.py QFN, 20 Pin (https://www.ti.com/lit/ml/msop002a/msop002a.pdf), generated with kicad-footprint-generator Soldered wire connection with double feed through strain relief, for 2 times 1.5 mm² wires, basic insulation, conductor diameter 0.65mm, outer diameter 2.3mm, size source Multi-Contact FLEXI-E 1.5 (https://ec.staubli.com/AcroFiles/Catalogues/TM_Cab-Main-11014119_(en)_hi.pdf), bend radius 3 times outer diameter, generated with kicad-footprint-generator Mounting Hardware, inside through hole 3.3mm, height 12, Wuerth electronics 9776050960 (https://katalog.we-online.com/em/datasheet/9776050960.pdf), generated with kicad-footprint-generator JST PUD series connector, S12B-XH-A (http://www.jst-mfg.com/product/pdf/eng/eXH.pdf), generated with kicad-footprint-generator Samtec HLE .100" Tiger Beam Cost-effective Single Beam Socket Strip, HLE-113-02-xxx-DV-A, 13 Pins per row (https://www.hirose.com/product/en/products/DF13/DF13-2P-1.25DSA%2850%29/), generated with kicad-footprint-generator Samtec HLE .100" Tiger Beam Cost-effective Single Beam Socket Strip, HLE-141-02-xxx-DV-BE-LC, 41 Pins per row (http://suddendocs.samtec.com/prints/hle-1xx-02-xxx-dv-xx-xx-xx-mkt.pdf, http://suddendocs.samtec.com/prints/hle-dv-footprint.pdf), generated with kicad-footprint-generator Molex KK-254 Interconnect System, old/engineering part number: A-41792-0017 example for new mpn: 39-30-0120, 6 Pins per row (http://suddendocs.samtec.com/prints/hle-1xx-02-xxx-dv-xx-xx-xx-mkt.pdf, http://suddendocs.samtec.com/prints/hle-dv-footprint.pdf), generated with kicad-footprint-generator Hirose series connector, B04B-JWPF-SK-R (http://www.jst-mfg.com/product/pdf/eng/eJWPF1.pdf), generated with kicad-footprint-generator connector wire 0.25sqmm double-strain-relief Soldered wire connection with feed through strain relief, for 3 times outer diameter, generated with kicad-footprint-generator Molex Pico-Clasp side entry Molex PicoBlade series connector, SM14B-SRSS-TB (http://www.jst-mfg.com/product/pdf/eng/eSH.pdf), generated with kicad-footprint-generator Soldered wire connection with feed through strain relief, for 6 times 2.5.
