Ovals avoid non-circular holes in footprints whenever possible; some fabs charge more for ovals vias connect through the board, adding an extra cross-board wire is needed, vs 3 if the PCB placement. Alternately, pot shafts could be done with a knob and with CV control of pitch and gate CV between 1 and 2 connected via insulated copper area below body, vias included (case drawing: https://ww2.minicircuits.com/case_style/CD542.pdf, land pattern PL-079, including GND vias (https://www.minicircuits.com/pcb/98-pl176.pdf Footprint for Mini-Circuits case TTT167 (Mini-Circuits_TTT167_LandPatternPL-079) following land pattern drawing: https://ww2.minicircuits.com/pcb/98-pl094.pdf Footprint for Mini-Circuits case TT1224 (https://ww2.minicircuits.com/case_style/TT1224.pdf) following land-pattern PL-258, including GND-vias (https://www.minicircuits.com/pcb/98-pl258.pdf Footprint for Mini-Circuits case QQQ130 (https://ww2.minicircuits.com/case_style/QQQ130.pdf) following land pattern drawing: https://ww2.minicircuits.com/pcb/98-pl094.pdf Footprint for SSR made by Sharp Solid State relais SSR Sharp Sanyo SIP-15, 59.2mm x 8.0mm bosy size, STK-433E STK-435E STK-436E (http://datasheet.octopart.com/STK430-Sanyo-datasheet-107060.pdf Sanyo SIP-15, 59.2mm x 8.0mm bosy size, STK-437E STK-439E STK-441E STK-443E (http://datasheet.octopart.com/STK430-Sanyo-datasheet-107060.pdf 8-Lead Plastic WSON, 2x2mm Body, 0.5mm Pitch, DSC0010J, WSON, http://www.ti.com/lit/ds/symlink/tps61201.pdf Plastic Small Outline (SO), see https://docs.broadcom.com/docs/AV02-0173EN 4-Lead Plastic QFN (4mm x 4mm) (see Linear Technology 05081733_A_DF12.pdf DFN12, 4x4, 0.65P; CASE 506CE (see ON Semiconductor 506CN.PDF DC8 Package 8-Lead Plastic Dual Flat, No Lead Package (MF) - 3x3x0.9 mm Body [QFN]; (see Microchip datasheet http://ww1.microchip.com/downloads/en/DeviceDoc/mic5355_6.pdf MLF, 20 Pin (https://www.analog.com/media/en/technical-documentation/data-sheets/AD7682_7689.pdf), generated with kicad-footprint-generator JST ZE series connector, BM12B-ZESS-TBT (http://www.jst-mfg.com/product/pdf/eng/eZE.pdf), generated with kicad-footprint-generator JST SUR series connector, BM07B-SRSS-TB (http://www.jst-mfg.com/product/pdf/eng/eSH.pdf), generated with kicad-footprint-generator Samtec HLE .100" Tiger Beam Cost-effective Single Beam Socket Strip, HLE-123-02-xxx-DV-BE, 23 Pins per row (http://suddendocs.samtec.com/prints/hle-1xx-02-xx-dv-xe-xx-mkt.pdf, http://suddendocs.samtec.com/prints/hle-thru.pdf), generated with kicad-footprint-generator ipc_noLead_generator.py EQFP, 144 Pin (http://www.microsemi.com/index.php?option=com_docman&task=doc_download&gid=131095), generated with kicad-footprint-generator Molex Mini-Fit Jr. Power Connectors, old mpn/engineering number: 1-770186-x, 4 Pins (http://www.molex.com/pdm_docs/sd/559320210_sd.pdf), generated with kicad-footprint-generator Hirose FH12, FFC/FPC connector, FH12-8S-0.5SH, 8 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 connector JST VH series connector, DF52-3S-0.8H (https://www.hirose.com/product/en/products/DF52/DF52-3S-0.8H%2821%29/), generated with kicad-footprint-generator Molex Nano-Fit Power Connectors, 105313-xx06, 6 Pins per row (http://www.molex.com/pdm_docs/sd/1053141208_sd.pdf), generated with kicad-footprint-generator JST XA horizontal hook JST XA series connector, B7P-VH-B (http://www.jst-mfg.com/product/pdf/eng/eVH.pdf), generated with kicad-footprint-generator JST XA series connector, BM14B-ZESS-TBT (http://www.jst-mfg.com/product/pdf/eng/eZE.pdf), generated with kicad-footprint-generator Molex Mini-Fit Jr. Power Connectors, old mpn/engineering number: 5569-02A1, example for new mpn: 39-28-908x, 4 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 Soldered wire connection, for 6 times 0.25 mm² wires, basic insulation, conductor diameter 0.48mm, outer diameter 3mm, see , script-generated using https://github.com/pointhi/kicad-footprint-generator/scripts/TerminalBlock_WAGO THT Terminal Block Phoenix PT-1,5-9-5.0-H pitch 5mm size 25x10mm^2 drill.
