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...
And it's not quite the right profile.
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.
I have discovered that they were bought out by Summagraphics and is it
possible to get pens from some outlet in Romania, but again very expensive

But I guess I only need one then I can get its size then I suspect turning
them on a lathe to take some standard rollerball type refill might be
easier than 3D printing them...
I'll keep looking,
Cheers,
Gordon
