It mostly depends on whether you want to solder or crimp the wires, and if you 
want various locating prongs.

That said, I'm fond of these:

http://www.digikey.com/product-detail/en/amphenol-fci/8656351064LF/609-1473-ND/1001787

These have gold flashed phosphor bronze contacts, you don't have to cut them 
out of a strip, and have
a nice barrel you can crimp or solder.  In singles, they're 12 cents apiece, 
but you can get a hundred of them for US$7.11
or if you're going to share with a bunch of people, a factory package of 500 is 
$29.40.

If you want square pins with some locating tabs, these are decent (although not 
gold flashed):

John,

Holy cow, lots of choices! Are there some in particular you reccomend? 
I'd hate to get a bunch of the wrong ones.


Are there others out there that might want some? No promises on it 
working out but I am going to try.


Jonathan




I am currently using some pin sockets scrounged from common old 
sockets, I think from a 9 pin.


Those are a good choice, I buy them in bulk and use them myself.  You 
can buy just the contacts, just narrow the search by "female pins", 
and whether you want crimp, solder, or whatever:

Re: [neonixie-l] PIxie tube 3D socket

[Jonathan Peakall]

John,

Ordinarily I would do just that. However, the nephew is getting the 
printer and I'd like to learn how to use it. And there are some 
advantages to the printer. For example, I ca make a couple of "ears" on 
the side with mounting holes and make a horizontal or vertical socket.


However, I'm going to order some of this polymorph, I can see where it 
is handy for many things.


Luckily, as far as 6 goes, the nephew is buying the printer and he is 
expected to bring the libations for during and after assembly of the 
printer!


Jonathan


1] Get some pin sockets, scrounged as you describe above

2] Get cylinder from old adhesive tape tube

3] Put pin sockets on tube pins, to suit tube available

4] Centre/center tube and pins within cylinder (depending on whether you follow 
proper English or Noah Webster's artificial dialect of the aforementioned 
language)

4] Melt polymorph in cup of hot water and squidge it into the cylinder, around 
the pins - squidge is a technical term (ignore it for now, you don't need to 
know)

5] Pop the socket out of the cylinder when the polymorph has solidified

6] Buy much alcohol with the money you have saved from not buying a 3D printer, 
pour and enjoy the time you saved not making a 3D model

Job done,

John S

Nice homebrew socket.

I, too, am finalizing a 3D printer purchase-decision. Even though my 
first-print will be a nixie socket (imagine *that*), I plan to use a 3D 
printer for other purposes, so it's not really a cost-savings measure if I 
decided not to buy it.

In my case, the ability to print nylon objects is the tie-breaker, because 
it's more durable than PLA or ABS.

How much raw material is needed, say, for the socket in the picture you
attached? Weight, I mean. I see it comes at about 4 USD every 100 grams
from the Far East. Could be a nice family DIY material too, so I could buy
some for you-never-know ;-)

Thanks,
Paolo

Some of the 3D printed sockets use Molex pins to provide side spring contacts 
(there's an 11 pin sub magnal socket on Thingiverse that works this way).

Those are a good choice, I buy them in bulk and use them myself.  You can buy

[neonixie-l] PIxie tube 3D socket

[Jonathan Peakall]

HI All,

In a couple of weeks, I'm going to be helping my nephew to assemble a 3D 
printer. One of the first projects I would like to use it for is to make 
some B9012 Pixie tube sockets.


I've never used a 3D printer, so it is all new to me. The data sheet I 
have has a good mechanical drawing for a starting point. Does anyone 
know of an off the shelf product I could use for the pin sockets? I am 
currently using some pin sockets scrounged from common old sockets, I 
think from a 9 pin.


And any other advice would be much appreciated. If I can make something 
that works, I should be able to help out any other list members that 
might need some.


Jonathan
