ball and socket chain links with hole through
Description
I think i will add some parts over time, like a housing for some leds.
There is also a flange that i didn't print yet. Who is first on this?

Defiantly worth printing 4 or more at a time as they print a lot better as it gives the layers chance to cool.
Fantastic!
It would be even great if you could post your BallSocket part with the socket features suppressed. I can only import the sldprt as a STEP file, and am having issues removing the socket. Having just the ball part and the "neck" below it would allow the rest of us to take the important bit and sim
ply add our own flavor to it.
BallFlange has issues for me because the fitment with the socket isn't very tight. BallSocket to BallSocket are perfect, however.
Additionally, a groove around the outside of the socket to allow an o-ring to be placed around it would be awesome! This would improve
clamping on the ball, which someone else already mentioned, and it would give it some grippiness as well.
These are great for making your own "helping hands." Great work!
Nice!
I'd like to make a clamp mount for the bottom end, and a 40mm fan mount for the top end... any chance you could publish your dimensions? or upload a step file?
Oh, and I forgot to mention a possible improvement to the design:
A lip around the 'socket' end of the model, to accommodate a rubber band wrapped multiple times.
The idea is the band compresses the socket around the ball, increasing the force required to move the joint thus increasing the weight it can hold. The band could also serve as a rubber surface, improving grip if used in a similar manner to the gorilla pods.
Brilliant!
I tried to design these things but couldn't get a model that worked as desired.
Then i realised my early prototypes were good enough for making snap together building blocks, a few revisions later and Beco blocks were born.
Glad you triumphed where i failed, I'm eager to print some.

Wow I've been meaning to try this since forever but I didn't know how to approach the problem. Awesome job!
Delimitation aside, I believe that this is a fabulous design that fills a general need that has not otherwise been addressed. It is definitely on my list of things to print once my Thing-O-Matic arrives in its cardboard chariot.
Great work!
I like the idea, but the printing orientation will make it prone to delimitation. They will be stronger if the design is adapted to be printed on its side, more like Beco Blocks: http://www.thingiverse.com/thi...
I recycle the extrusions, melted into acetone, and then paint this on. I have little jars of each color I work with.
I have a pretty simple work around for delamination that's been really effective for me. JB Weld Epoxy cut with a bit (not more than 1/10th of total volume) of denatured alcohol. The alcohol isn't essential, but it does make it a bit runnier which is nice for filling cracks or lets you add various things to color/texture it.
Paint it on in a thin coat, let it dry for an hour then take a hair dryer to it. Once it heats up it will get CRAZY runny again and that lets you do surface finishing if you like.
Let it dry overnight. Sand/work as necessary. Thin coats can even retain some flexibility. If you add too much alc
ohol it seems to dry really brittle.
I see the possible danger of delamination, although my parts printed pretty strong. Everything except the sphere printed solid and the pieces snap together without any cracking noises. I played around with them for some time now and they seem to hold up pretty well. I wanted pretty pieces with a hole so i can guide some wires through the parts and put a light at the end.

Thanks, I've been making these and mashing them up with the printable pcb vise to vastly improve Helping Hands. I will post that when I get a pic.
The Ball Flange is definitely undersized- the ball is too small and I had to measure and print at a larger scale to make it tight.
But, the strength is no problem at all- print at at least 50% infill to make the lips strong, and 0 extra shells so that the neck gets printed solid. If you don't clean them up too much they have more friction and the resultant "snake" is very stiff- good for holding things.
I forgot to mention; print the flange at 107% or 108% to make it fit the others properly.
