Where to find small knobs for HP 54601A Oscilloscope

[Irving]

As per topic subject, the small knob for trigger level has disintegrated and some of the others are looking dodgy.  I'd like to keep it original if possible..  where can I source them from?

You just can't as they are not manufactured anymore then, you've got options:

#1 - Source for used or maybe old stock (ebay?), witch will pretty much worn out again as degraded plastic behaves weirdly.
#2 - 3D print them in resin...

Thanks,

I figured that might be the case....

Have you checked this thread for an already existing 3dp model ?

Thanks for that, sadly I can't see anything suitable there or on some of the external links. I'll have to CAD something myself....
