Eric Smith and I have been looking for these for a long time.
They are BASF floppies, though.
As are mine... ( some 3M and CDC disk also part of the haul )
Does that mean they will need baking ?

please.
Has anyone ever seen one? I had an idea it used a silvered-paper and
burned it off? or am I mis-remembering.
I'm seeing one right now, as my VT52 has such an unit. Never seen one in action
though.
I can put up some pics if desired, let me know what you need.

Tektronix 405x tapes aren't QIC
They are 3M DC series cartridges, but the encoding is not a QIC standard.

You can 3D-print replacements.
Use Innoflex filament, 100% fill-in and the following OpenScad formula :

which Innoflex filament? There are several different hardness variants.
I used Ninjaflex 3DNF0517505, but that is because it is the only TPU type

I would rather use a somewhat harder variant.
