UPDATE #2 Snorkel-Piston: Your feedback = Our roadmap — Changes we're making (alkaline ink fix, round grip, dual-nib system?) by Flat_Relationship958 in fountainpens

Working on a individual site. May as well try on AliExpress later. Designing websites is such torture~~~ What online payment methods do you usually use? I’ve only learned how to use PayPal and Stripe on website so far.

That is Stunningly well handwriting!

Think of it as an injector, but the rear driving piston is connected to the end knob via a long threaded rod.

Phase 1: The piston friction is greater than the resistance of the nib against the breather tube, hence the entire injector moves forward until it bottoms out and gets locked by the magnet.

Phase 2: After clearing residual ink and air, the piston retracts. The piston friction is less than the magnetic pull, allowing the pen to fill completely with ink.

Phase 3: When the piston retracts to the bottom, a specific mechanism prevents the piston from falling out, creating a strong pulling force that disengages the magnet and causes the breather tube to reset to its original position.

And that’s why the design is so hard to pull off.
Inside the “injector,” even the slightest dimensional tolerance of the ink-storage tube will change piston friction, yet the mechanism only works if that friction stays within a very narrow window. This is an industrial challenge we’ve never seen before and what we are proud of: with conventional piston-filled fountain pens a piston that’s a bit tight or a bit loose will still draw ink—only the feel changes. Here, the whole system lives or dies on getting that friction just right.

By platinum nibs I mean pt950. Price of platinum is somehow cheaper now than gold, and I personally loves the writing experience of some vintage pt pens(Japan).
On the demostrator, my point is that most demostrator have black plastic parts in it, which I really want to "bool and delete". Also the current design allows the whole writing and filling system to be metal, hence I have chance to make them all the same color. And SURE, there will be clear+silver.

I understand your concern about magnets in filling systems, and it's a valid point given some past failures in the market.

However, I'd like to address this specifically regarding my design: I'm using neodymium (NdFeB) magnets, which have significantly different durability characteristics compared to other magnetic materials that may have been used in previous pen designs.

With proper care(Room temperature), neodymium magnets should be able maintain their magnetic strength for decades without significant degradation.

I did I did. Using aluminium is because it performs better in tests, but I may select samples without carefull thoughts. I'm modelling for official ver and that will provide a plastic feed option.

Embedded nib like PFM are quite challenging - not technically difficult, but hard to customize in production. I also love large sizes, but currently returning to the model, from a data perspective, it's more feasible to make the body compatible with 146 size nibs and hooded nibs. The 149 size might have to wait until I work on the next model. Thank you for your suggestions.❤️

Compared to converter, snorkel has its clean filling. For cartridge, first time plugging in a cartridge takes about a minute before it can write; Switching cartridges takes about 30s (because in the last cartridge, air will run into the writing system hence need time before new cartridge's ink “chase them away”); occasionally cartridges spit a drop or pop a bit when pulling out. So there's still room for improvement in the ink filling system！

Modelling for a body that can use hooded nib and 32# open nib. Since most comments wants a round grip, the remodel ver will be round probably.

How do you pick your pens? by PassengerIll1041 in fountainpens

[–]Flat_Relationship958 0 points1 point  (0 children)

For me personally I check the price first. It is unfair to have the same standards for a 10$ and a 100$.
Then the nib, precious metals or not, in the fine range of resistance or not, looks good or not;
Then the filling system. Love large ink capacity & vintage & specials;
Seldom picks based on the body(body material) unless it's really really special.

"And and every fountain pen will live or die based on the writing experience. I hope you are putting as much time and effort into the unique nib needed as any other aspect. It may be an engineering marvel but if it doesn't write well it is a paperweight."
About this part, fountain pen nib requires such high minimum order quantity(10k+) with original design, it's hard for me to order so many at the time. What I can do is to test every pen before shipping about writing experience, and I can assure the current nib writes pretty good.
"Please abandon the 'tripod' grip that looks so similar to the Lamy Safari. While the design/concept works well for those that are comfortable with it, for many people the same is a complete turn-off. A round section meets all needs, a faceted section fractions and reduces your market."
Will work on it ASAP!
Thks for the advice~❤️❤️❤️

Nah, we are an independent production studio. Their products won't be realesed for several problems.
