Has Anybody Tried To Fabricate Or 3D-Print Parts? (Mark 1 Vacumatic Blind Cap Although Anything Else Also)

Has anybody tried to fabricate, with or without a 3d printer, any parts? especially Parker 51 vacumatic blind cap parts? esp on the Mark 1?


I have a Blue 51 Mark 1 (vacumatic with the plastic plunger and all-plastic blind cap) that I think is a a demi because it was short, but the diameter is the same so i don't think it matters. I do not care if the color is the same (not like pink or a bad looking color though) or if it is even the same shape since it isn't a very intriguing or necessary shape anyways. The bottom lip has a chip that is about 90-120 degrees around the bottom but not deep, so it doesn't affect usability but is clearly visible by as breaking the continuity/seam and as a kinda "hole" in the side. I'm thinking it might be hard to 3d print usable threads, but I think the following things could be done.

1. Print something that vaguely resembles the cap and have an inset with the threads in another material like homemade casein (milk protein plastic), modeling clay, sugru (moldable silicone that stays set once cured), or a Thermoplastic like InstaMorph (plastic that can be reshaped as well as finished in several ways)

2. Have the whole thing one of the materials listed and hand shape it or even better make a mold of the current cap.

3. Have it 3d printed or one of the materials listed and fugure out a way to have it attached another way than threading. I haver some ideas but not really sure of the best way. I am thinking like some sort of small locking or snap mechanism or like locking friction threads.

If anything I could have like a friction-fit end cap with "arms" that run down the pen a little, and if the whole thing or at least the "arms" are made of the silicone sugru it would almost definitely grip if it is what I imagine and double as a roll-stop as I don't usually post even when the pen is short.


As long as it works, and doesn't cost much more than an actual blind cap or I can sell another to offset the cost I am probably going to make my own blind cap for at least the experience/fun/challenge/new techniques so if you are interested contact me.

And not only do I mean a 3d-pprinter I have cheap enough access to could not print usable threads I couldn't design matching threads. Also, I plan that any "hack" I use can be taken off without damage to the pen unless it works as well and looks better that a normal blind cap

A replacement blind cap would run about 10 US for a cedar 51. I would think replacement is the easy way to go.

But not as much fun. You could find your pen in a dark room if you 3-D printed a cap in glow in the dark material: http://www.argylematerials.com/abs-p430-refill-glow-in-dark-volume-56-cu-in/

I'm doing more for the fun of making my own blind cap. I could buy a cap but it would be more interesting to make my own, plus the one I have still works so I don't really have to buy another cap anyways

That sounds like fun... could be printed in nylon or PET or ABS

I dont know how a blind cap looks like though If you design it, I will print it for you and ship it to you

      Ah Ruaidhri ya wee heid banger, you do indeed have an Irishman’s way wid dose words now. I’ll be from outer Aberdeenshire up in the blizzard riven braes of the Grampians.  Amateur medicine and surgery is it? Well what noble aspirations you do possess, we need to encourage such noble experimentations.  I pondered on leaving my own battered shell to science, but, until I read your pearls of wisdom and lament, I had comedown on the side of leaving my body to Findus frozen foods.  However, your rema

      Hi Smug Dill,   Nice project.  If it were me, I'd cover stuff like: - nib types available, i.e. styles, materials (SS vs gold), flex vs nails; - filling systems (I love the "thingie" comment) and how once can use them in practice (e.g. fill cartridges with a syringe); - pen body materials and their consequences (pen not balanced of too heavy and big for the hand); - and, whilst you've made it clear that you do not like vintage pens, a discussion of these beyond "I d

      Thanks for your input! Yes, not putting wood in the list of body materials warranting a mention was an oversight. I love pens with wooden bodies, but my main concern, or chagrin, is that I have not come across a wooden-bodied pen with a wooden cap that seals well. Actually, there is one, but it isn't really wood per se: the Pilot Custom Kaede's maple body is resin impregnated. All other wooden pens I have can dry out while capped and undisturbed; that includes several Platinum #3776 models.

      That looks pretty good. You might want to add wood as a material (with its weakness of staining) and mention urushi. And under ergonomic considerations, the size of section (slender pens vs chunky pens), and shape of section, and 'disturbances' such as the Lamy 2000 'ears' and Pilot Capless clip getting in the way might be worth mentioning. Also possibly a general section on things you can do yourself with a bit of care, with a bit of practice, and things that are strictly "don't try this a
