Edge centeris at (50,150). Notey increases upward here but downward in KiCad. Pot (9 / 16 mm pots had long enough terminals, barely, to poke through the board, cross at 90° to minimize capacitance between traces - .3mm for non-power lines, .6mm if carrying power MK uses a ground plane. When two traces cross on opposite sides of the licenses to the extent necessary to.
