... remove treble button legs on CBA?

[vtfanta]

Hi,
I've bought a 120 bass CBA Weltmeister Grandina (I suppose, there is no model name). It is in tune amd in a pretty good shape apart from the legs of treble buttons. The instrument is from the 60s and the original plastic ones are a bit worn. One or two buttons can't be even screwed in anymore. I've managed to take the keyboard apart, but now I can't easily take the plastic legs off.

I want to measure them to make 3D-printed replacements. Does anyone have experience removing these plastic parts? They seem to be glued in, so perhaps heating up with a soldering tool? Also, if I wanted to get the original replacements, where do the suppliers get them from? I don't see these when browsing through accordion parts online.

PS: Merry Christmas, everyone

I'm sure you can buy these parts from Carini (www.carinidena.it). I think the originals are all made out of celluloid, but they might be a different plastic now.
I think the design is simple enough to make replacements on a 3D printer. It's probably best to make them out of ABS plastic as it is more durable than for instance PLA.
But the first question to ask yourself is: why would you want to replace these "stems" or "legs"? From just looking at the pictures they look fine. Some obviously were replaced in the past and could be painted black so you cannot see that any more. But I would only attempt to replace some if they are really broken.

I agree, don't make problems where there aren't any.
The only 'fault' you've described is that some of the button fixings are not secure anymore and the screw holes in the plastic pegs have become loose. It's a very simple matter to fill the holes and make a new, secure fixing for the button.

I'd like to take the opportunity to say 'Happy Xmas and Good New Year' to all the people on Accordionists Forum.
