Titan Pens Ranga Model 8: A 3D-Printed Fountain Pen That Shows Real Craft Evolution
The Ranga Model 8 from Titan Pens is a piston-filled, triangular-profile fountain pen built around a number seven JoWo nib, with refined proportions and standout comfort.
Introduction
Some fountain pen makers refine their craft slowly and visibly, and Titan Pens in the UK, run by William Shakour, is a great example. Every pen he makes is 3D printed, and watching the designs evolve over a couple of years tells a story of continuous improvement. The Ranga Model 8 sits near the top of that progression: a triangular-profile pen built around a number seven JoWo nib, with the most refined proportions and finish of the lineup.
This review looks at what the Ranga Model 8 offers, who it suits, and why it has earned a permanent spot among larger pens worth serious consideration.
Who This Product Is For
The Ranga Model 8 is unmistakably a large pen. If you enjoy big, girthy pens with generous ink capacity, this design fits that preference perfectly. The triangular profile, a shape the maker clearly favors, gives the pen a distinctive look while the faceted section stays comfortable in hand.
It is also aimed at enthusiasts who want a pen built around a specific nib. This model was made to house a number seven JoWo nib, and the result is a very refined writing package. If you prefer slim pens or small hands make oversized pens awkward, this may not be the right fit, but for fans of larger pens it is hard to hesitate.
What Makes the Ranga Model 8 Special
The clearest sign of refinement is the detailing. Earlier designs in the line had bolder, more prominent threads and slightly bulkier proportions. The Ranga Model 8 carries a clear logo filled with gold, a smooth well-fitted cap, and threads that operate cleanly without standing out. The faceted section is among the most comfortable the maker has produced, and the overall silhouette is a little less bulky than the earlier triangular model, with proportions that simply work better.

The finish quality also shows the progression. The material is a beautiful gray tone, and the polishing on later models is noticeably smoother and more light-reflective than on earlier pens. Side by side, the difference is easy to see.
Design and Materials
The Ranga Model 8 uses a triangular profile with rounded facets, similar in spirit to a Reuleaux triangle design. The section is faceted and shaped for comfort, and the barrel is large enough to hold a serious amount of ink. The cap unscrews simply and seats well, and the flat-top styling keeps the look tidy.
Like the rest of the lineup, the pen is 3D printed, which is part of its appeal: a craftsperson iterating on geometry, polish, and proportions with each new model, and it shows in the result.
Filling System and Ink Capacity
This is a piston-filled pen with enormous capacity. The entire barrel fills with ink, so the pen simply does not run dry in normal use. It keeps writing and keeps going, which pairs beautifully with a wet, broad writing experience.

For writers who dislike carrying ink around or constantly refilling, a piston filler with this much reserve is a genuine practical advantage, not just a novelty.
Writing Experience
Built around a number seven JoWo nib, the Ranga Model 8 delivers a smooth, comfortable writing session. The section fits the hand so well that it is genuinely hard to put the pen down, and the big ink capacity means nothing interrupts the flow.
A wet, high-capacity pen does demand ink-friendly paper. With broad, wet nibs, some feathering can appear on less forgiving paper simply because so much ink reaches the page. On good paper, though, the experience is excellent.

Pairing the gray material with a matching gray-toned ink is a popular combination for this pen, and once inked, many owners never feel the need to change.
Things to Consider Before Buying
The size is the main consideration. This is a big pen, and the faceted section helps, but the overall girth means smaller hands may find it less comfortable. It is a pen for people who already know they like large pens.
Also worth knowing: some other models in the Titan Pens lineup post, but the triangular-profile pens generally do not. If posting matters to you, check the specific model before ordering.
How It Compares Within the Titan Pens Line
The lineup shows clear evolution. The first 3D-printed faceted model offered a large ink window and piston filling, but with coarser texture and bolder threads. A subsequent Reuleaux triangle version brought smoother texture and finer threads. An oversized eight-inch eyedropper model, holding roughly 14 ml of ink, pushed polish and translucency even further. The final torpedo-shaped model in the lineup adds a flat-top cigar shape, smooth threads, and the ability to post.

Placed among these, the Ranga Model 8 represents the point where proportions, gold-filled logo detailing, and section comfort all come together. It is the model that feels most resolved.
Buying Advice
If you like bigger pens with triangular profiles and huge ink capacity, the Titan Pens Ranga Model 8 deserves a place on your desk. It is a piston filler that does not run dry, a section that fits the hand beautifully, and a design refined by a maker who clearly cares about continuous improvement. Check the maker’s current nib options and availability directly when ordering, since each pen is built to order around a chosen nib.
Conclusion
Titan Pens demonstrates what happens when a craftsperson keeps iterating: finer threads, better polish, more refined proportions, and genuine comfort. The Ranga Model 8 captures all of that in one pen. For enthusiasts of large, high-capacity piston fillers with distinctive faceted styling, it is an easy recommendation.
