Hex Shaped Punch

Oh I like what you've done. It's a bit pricey though just to make some knobs.

I guess I could make these on the CNC, I hadn't considered that.

You won't like my answer.  I do it really easy in any size I want... with my Shaper Origin

Honestly, it's a great tool for doing weird little stuff like this.  I make all kinds of flavors of custom knobs for various things.  Attached is a cherry knob for a walnut belt tensioner I made for my lathe (also made with Origin).

what software do you use to design these?

For both of these parts, just Affinity Designer.  Origin uses SVG files so the 2D is all I need for simple stuff.  If I am doing something more complicated I might use SketchUp or Fusion360 and there are plugins to convert to SVG.
