Now, I might be able to design and print some replacement items (in
PLA) but in the short term I was wondering if there was a suitably
'strong' tape that might do what was required.

And that would be something that could be bound round the inner
section tube (at the key points at the different positions etc) so
that it can still be easily slid into the larger tube(s), offer some
resistance to the tubes twisting inside each other (axle sections
mainly) and just help to keep the whole thing from clanking when it
goes over holes and bumps.

eg, Insulating tape would be too soft and probably just get crushed
when built up to the required (~1.5mm) thickness so I was wondering if
a metal (chrome) tape might work better?

a 3D printed 'sleeve' would be basically a square box section, about
40 mm long with ~1.5mm thick walls and rounded corners. It would want
to be a close interference fit on the inner section tube (and possibly
glued / pinned into place) and a light sliding fit on the inside of
the larger section tube.

Ideas?

Cheers, T i m




Handlebar tape may have some of the properties you want, though there are
different types so you may need to look at what particular properties a
version has.

Elsewhere in the thread someone mentioned chrome tape, another metallic
tape that is fairly tough is the aluminium tape intended to hold /seal
sections of flue pipe together.
