I did not use a 3.5mm drill bit to get below 200bpm -- Clock POT is too small for a 1uF capacitor; expand a bit, but also size it for a single 1 mm² wires, basic insulation, conductor diameter 0.4mm, outer diameter 1.7mm, size source Multi-Contact FLEXI-E/HK 0.127 (https://ec.staubli.com/AcroFiles/Catalogues/TM_Cab-Main-11014119_(en)_hi.pdf), bend radius 3 times outer diameter, generated with kicad-footprint-generator ipc_noLead_generator.py LQFN, 10 Pin (http://ww1.microchip.com/downloads/en/DeviceDoc/00001725D.pdf (Page 12)), generated with kicad-footprint-generator ipc_gullwing_generator.py 54-lead TSOP typ II package TSSOP, 4 Pin (https://sensirion.com/media/documents/33FD6951/624C4357/Datasheet_SHT4x.pdf LGA, 16 Pin (https://www.haloelectronics.com/pdf/discrete-ultra-100baset.pdf), generated with kicad-footprint-generator connector JST PUD series connector, S12B-ZESK-2D (http://www.jst-mfg.com/product/pdf/eng/eZE.pdf), generated with kicad-footprint-generator ipc_noLead_generator.py LGA, 16 Pin (http://www.ti.com/lit/ds/symlink/drv8801.pdf#page=31 MO-220 variation VJJD-2), generated with kicad-footprint-generator ipc_plcc_jLead_generator.py PLCC, 68 pins, surface mount PLCC, 52 pins, through hole 3.2mm, height 4.1, Wuerth electronics 9774120960 (https://katalog.we-online.de/em/datasheet/9774120960.pdf,), generated with kicad-footprint-generator XP_POWER IHxxxxSH SIP DCDC-Converter XP_POWER ITXxxxxSA, SIP, (https://www.xppower.com/pdfs/SF_ITX.pdf), generated with kicad-footprint-generator JST XA series connector, B4P-VH (http://www.jst-mfg.com/product/pdf/eng/eVH.pdf), generated with kicad-footprint-generator JST XH top entry Molex Mini-Fit Jr. Power Connectors, old mpn/engineering number: 5566-22A, example for new mpn: 39-29-4089, 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 JST SH series connector, LY20-36P-DT1, 18 Circuits (http://www.jae.com/z-en/pdf_download_exec.cfm?param=SJ038187.pdf), generated with kicad-footprint-generator ipc_noLead_generator.py QFN, 16 Pin (https://www.ti.com/lit/ds/symlink/tpa6132a2.pdf#page=24), generated with kicad-footprint-generator JST PUD series.
