When I linked to Studio Neat’s Mark One: Apollo Edition Kickstarter campaign the other day, I mentioned that I use a Mark One using Zebra ink refills, thanks to a 3D-printed converter. A few readers asked how to obtain this converter. I’m linking here to the model. I don’t own a 3D printer — the guys at Studio Neat made this for me as a favor — but if you have access to a 3D printer this should get you started.
The refills you need are the JSB-04 (0.4mm, very fine) or the JSB-05 (0.5mm, fine), and, of course, you can get them at JetPens.
