I designed this model for a macro pad project I worked on. It's designed for 6 mm D-shaft rotary encoders and has been tested with the Bourns PEC11R-4215F-S0024. It provides a nice friction fit while still being easy to remove.
Customization Instructions:
I used a custom printable knurling feature in Onshape to create the knurls on this model. If you'd like to edit them or change the appearance of the knob, you can find the original Onshape model here:

Print Settings:
I didn't include any print files because it's a pretty simple print. Just import the model, place it on the closed end face, and use these settings:
0.10 mm layer height - for detail
100% infill
Then hit print!
