Looks like a job for 3DP to me. Setting aside the plastic rot you describe (yuckyputz!  :P), I quite like the beefy ceramic substrate I'm seeing there. I'd try to find a way to fix them.

I think it might be easier (and more durable/reliable) to just cut the missing/broken shaft in a skinny metal rod, drill a tiny hole in the center of the knob and press fit the rob into the knob.  ;D

But the problem remains that the original design is flawed, in that there is nothing that keeps the shaft/knob from lifting out of the bore in the trimmer/ceramic base. Shaft does not "clip" into the trimmer. It's just a smooth skinny cylindrical shape. It holds into the bore merely thanks to interference. There is nothing to ensure "clamping" force onto the knob to make sure the wiper is making a good reliable contact with the track on the ceramic base. So if one could implement such a mechanism, that would be a nice improvement.

Obviously in practice it's not worth the trouble, so long as modern replacements are available, and at a reasonable cost.

But I guess as an exercise, just for the fun of it, yes you could try to make something with your 3D printer(ssss)...

Just found out how much Russia fucked my pension today. 3 years of contributions down the shitter. I've just shit canned all contributions to it in the short term and will spend it on beer, floozies, scopes and power supplies  8)

So the standard reply to:

Interviewer: Mr. Bloke how are you going to spend your lottery winings?
Mr. Bloke: Well, I'll spend most of it on booze and women, and the rest I'll just fritter away.

Isn't that a paraphrase of something George Best said?    https://twitter.com/football__tweet/status/1362009651080884228?lang=en-GB

The correct attribution of that as a quote is to a Mr. Apocraphous Anonymal of 17 Acacia Avenue, Neasden. Some authorities differ, and attribute it to either a Mr. I.P. Freely or a Mr. Michael Hunt, both said to be residing at 16 Acacia Avenue, Penge.

Agreed, neat trick.

(Too long; can't be bothered to watch): Cut a wedge out of high temperature resisting silicone rubber, put it into a [improvised] holder, and use the edge of the wedge to squeegee/wipe solder off pads after heating them to above melting point.

And the culprit came up with the expected zero ohms resistance across it as expected. Lurking in the corner under the HV shield.

That's a rather colourful Tant you have here ! So far I had only seen them yellow orange red or blue, now I see they even exist in flashy green.
Soon we can make a rainbow out of them.

Any other colours I am not aware of ?!  ;D
