MK's PCB livestream - avoid non-circular holes in footprints whenever possible; some fabs charge more for ovals PCB layout: front, back How 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 17.5mm panel hole+snip off pin, add holes for a 1uF capacitor; expand a bit, but also size it for a fee. 2.
