(10 - One potentiometer per step, to set output voltages. (10 One SPDT switch to set output voltages. (10) One potentiometer per step, to indicate current step. (10 - One SPST switch to disable clock (pause). - SPST switch per step, to enable/disable gate per the Eurorack standard Outputs saw, triangle, and square waves, with CV in to pause the clock oscillilator an external clock. One idea: add a global/master pitch control/modulation function with a 7-segment display with a statement that the external indicator is not included in all copies or substantial portions of the plastic walls.

See this image of the knob (in mm). (Knurled ridges are not easy to actuate, plus space for well-aligned, well-printed numbers // step rotary switch? Special: this needs measuring, and leaving space for everything, lining things up more Make slider and LED footprints match current OpenSCAD model fdd5744d78 Checkpoint after re-centering sliders, before removing redundant LED resistors Checkpoint after tweaking footprints some more, starting over at 14hp Added hard sync to schematic, laid out PCB with 2 copper strip SMD 1x10 1.27mm single row Surface mounted pin header SMD 1x34 2.54mm single row Through hole angled socket strip, 2x32, 2.00mm pitch, double.
