And it's not quite the right profile.
Some more searching turned up an old reference to adapters for various plotters for
Koh-I-Noor "Rapidoplot" plotter pens, which I believe are the same as
Rapidograph minus the body for holding the pen in the hand. And another

<https://www.farnell.com/datasheets/99601.pdf> shows adapters for Mars technical
pens, that's another brand I remember for the same kind of pens. It mentions part
number 75PL03H10 and a search for that turns up a Rakuten website (in French) offering
it.

I have a HiPlot plotter - it's DMP-29, but I'm fairly sure it takes the same pens
as the DMP-2 which I also have but in a million pieces - but right now without pens.
I have been promised some but it may be many weeks...
I'm wondering if anyone has any old (or NOS?) pens for them? What I'm after is
the dimensions with a view to 3D printing new pens - or at least pen holders so I can fit
modern pens into. (There is no height restriction on the pen bodys)
Can anyone help?
Some searching turned up this:

Expensive... It's hard to be sure, but I wonder if a
standard Rotring (a.k.a., Radiograph) technical pen will work. Those were commonly used
in plotters, for example I remember using a Calcomp plotter with one of those. And those
are obviously refillable, and available in any number of sizes. Not to mention great
drawing tools to have around -- I wonder where mine is.
They have a stepped profile which seems different from other plotters of the era (HP,
etc.) so no different from inkjet cartridges now, I guess.
