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.

Looking at the documents for the DMP-29 those need an adaptor....

Nice, so that means such a pen would indeed be suitable.
Perhaps the adapter is merely a sleeve with matching threads for the plotter and the pen?
3D printing was mentioned, an adapter like that would be a simple exercise. (Ditto for
someone with a lathe.)
