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 square, hexagonal etc. Shafts. ≥30 means "round, using current quality setting". Setscrew_hole_faces = 20; // // knob_radius_top = 16; knob_smoothness = 20; // Diameter of base of round part of knob (in mm). (Knurled ridges are not quite parallel, but they're close. ## Assembly order I suggest the following procedure for assembly. As usual do the lowest components first — resistors and diodes — then sockets, ceramic capacitors, power header, transistors, film caps, electrolytic caps... Something like that.
