Replacement parts for CC121 (AI Knob)

Hi!
So, my kid has been at my studio and has managed to steal the AI Knob… I have searched everywhere but can’t find it. I have been searching for spare parts for the CC121 and have found the knob on an online store in America, but they only ship within the USA.

Where can I get this spare part (PS. I live in Sweden)

It doesn’t have to be that specific – it’s a generic knob, like a volume control. The shaft is 6mm, which is kind of standard. Maybe you even already have something in your studio that your kid hasn’t eaten yet that would work.

Just examples- I’m searching in the USA
