The file 'Fountain Pen – Full Size – Tapered #1 3D Printer Model' is (stl) file type, size is 2.6MB.
This is another pen design, included are sections for Jinhao #6 nib units, Jinhao #5 nib units, Hongdian #6 nib units, and Hongdian #5 nib units. Pick the one for the nib you have.
The end of both the cap and barrel are threaded for an insert, I have included a rounded one and a flat one for both sides, these would be pretty easy to customize for your own wants.
In the picture, to give a size scale is a Majohn P136, so these are full size pens, I personally think they look best with one of the #6 nib units.
I printed these with PLA+ with a 0.4mm nozzle, 0.8mm layer height. I used some supports on the rounded end caps under the lip, and for the very tall, thin barrel and cap, I did a ring of tree support just to keep them from getting knocked over. You can print these without the support, but I use them for sanity.
