This fits the Entune Premium head unit. Fits both Volume and Tuner knobs.
I'll upload installed photos later. They work really well and allow much easier manipulation of the knob compared to the super slick, and small diameter factory knobs.
I used PLA, but after a hot summer they aren't as snug as they were to start (but still work well enough to not bother making new ones using abs or petg)
They're the right size to modify the model to apply a small image or design to the face. I included the IPT in case there are any Inventor users out there.
