I needed some knobs for rotary encoders and rotary switches for a project I am working on ( fsx flight panels ).
.
They were printed at 100 micron setting on my Replicator 2, there is a channel a nut can be slid into, and then the screw clamps against the switch shaft.
.
The small rotary selector switch needs an M2.5 nut and bolt, and I had to hacksaw the bolt to shorten it.
.
The larger encoder knob needs am M3 x 12 mm bolt, and will fit without modification.
.
I have included the Fusion360 files.
