It is development of https://www.thingiverse.com/thing:2969193.
The goal was to use biggest o-ring from the set and make a big but still usable pen (for this new features in the pen design was made).
Still all previous versions and future one can be get from https://github.com/sanja-byelkin/SimplePistonPen . I included included snapshot of sources, but you easy can get them by:
git clone https://github.com/sanja-byelkin/SimplePistonPen.git
cd SimplePistonPen
git checkout V3
So ability for scaling was tested and fixed.
I did not polished the pen outside just to show how it looks like unpolished, but polished variant is better in ink removing after filling the pen.
Assemble, polishing, feeder and nib are the same as for the previous small model: https://www.thingiverse.com/thing:2969193 . Also there is photos to compare with the small model and Lamy Safari.
To make the pen default configuration additionally (except printed parts) required:
Nib #6 (it is nib size standard, can be used any nib (Peter Bock, Jowo, Noodler's, Jinhao, or even antique nib from some old broken pen))
Ebonite feeder for Noodler's ahab/konrad pen or selfmade ebonite feeder with diameter 6.3mm.
Two o-rings for piston (mine goes from some set of o-rings marked 2/3" - 1/2" bought in plumbers part of supermarket, see photo, external diameter of them is about 14mm, ring is about 2.5mm thick).
a bit of silicone grease
Sand paper or something else to polish inside tube with diameter 14mm (I used sand-paper 400, 800 and 1500 and put is with super-glue on printed cylinder which put on BBQ-steak).
