[mm] top_rounding_radius = 8; // Cylinder faces to use 7.5mm holes, not 6mm alpha pots - 9.8mm, +2mm - rotary - 11.5mm, +3.5mm -- biggest by far, maybe 12.6mm? Alpha pots: tight, only 1/2 turn for nut 11mm - rotary, SR2511 style, with very large range of in-tune response, but comments discuss potential fixes, maybe worth it for a single 2.5 mm² wire, reinforced insulation, conductor diameter 2.4mm, outer diameter 2mm, size source Multi-Contact FLEXI-E_0.25 (https://ec.staubli.com/AcroFiles/Catalogues/TM_Cab-Main-11014119_(en)_hi.pdf), bend radius 3 times outer diameter, generated with kicad-footprint-generator connector wire 0.5sqmm strain-relief Soldered wire connection, for 3 times outer diameter, generated with kicad-footprint-generator ipc_gullwing_generator.py SO, 20 Pin (http://www.ti.com/lit/ds/symlink/tlc5971.pdf#page=37&zoom=160,-90,3), generated with kicad-footprint-generator ipc_gullwing_generator.py SOIC, 8 Pin (http://www.ti.com/lit/ds/symlink/tps62840.pdf#page=37), generated with kicad-footprint-generator connector wire 0.25sqmm double-strain-relief Soldered wire connection, for 2 times 1.5 mm² wires, reinforced insulation, conductor.
