i tried doing something similar to this, did not work at all, the joints do not have enough friction in them to hold anything over 3 links.

Just a heads up for anyone else hoping to print this; none of these parts are sized properly for 3D printing. The holes come out too small and the joints don't fit together. Designer could have done better job of explaining how he got it to work in the summary. For example what material was used, what print settings etc. Either special print settings were used or the parts were filed or shaved down post print because the joints do not fit, at all.
Other helpful information might include Make/Model of 3D printer used and which program was used for slicing (accuracy varies).
A bit of reading to help you make better designs for 3D printing in the future:

LOL, you're seriously lecturing me with a makerbot article .... and being nice usually brings you a lot further....

Anyhow, material shrinkage varies a lot. Item was printed with standard settings in normal PLA, nothing special at all. I am using a Ultimaker, so mostly good prints out of the box. If you have any mechanical print, doing a (partial) test print never hurts.

I am being nice....
Yes I am pointing you towards that article because these parts are not even close to correct dimensions. Even when printed in PLA, the joints do not fit together, because they are sized incorrectly. Even after filing a good portion of material from them the fit is still terrible, the fins of the joint have to bend outwards to compensate and if not printed at 100% infill they break easily. The issue here wasn't print quality, its design quality.
I don't mind having to do post print shaving and cutting but this was so far off.... Only .10mm of tolerance was given for those joints to meet, meanwhile on average you have .50mm of expansion from both sides. Math is useful.
If you have a mechanical design, making the proper tolerance adjustments for proper fit never hurts. Might be okay if it was machined or injection molded, but this is to be 3D printed and therefore the appropriate considerations must be made. The equations in that article will help you get closer in the future, even with the variance in material shrinkage.

The smooth injection molded gopro mount I have handy even has about .50mm of clearance between the middle of female and the middle of male.

My one is VERY fragile. I broken in part in several places. not starting using it. I used ABS.

It is just too cool... And Thank's for the .RSDOC file I use Design Spark Mechanical and this was just what the doctor ordered.

This is pretty cool. I've printed the handle and cap so far. An arm piece is printing right now. My only suggestion is that the cap nut should probably be solid to make it easier to fill with sand. you could adjust the level of sand in the handle to be just right to be tight when the nut is put in. Right now that's impossible since it's hollow and there will always be empty space... to get it full you have to have sand all over in the threads which makes it tricky.

Thanks for the cool thing!

I filled in the handle cap and uploaded it in case anybody else is interested. It works better for me this way.

I made an adapter so this great handle system can be used for mobile phones and other devices. http://www.thingiverse.com/thing:908046

Ahahah dude that is too cool! You are awesome.

Ahahah dude that is too cool! You are awesome.

one arm is 18,2 cm

if you download the free CAD software "design spark mechanical" you can easily modify it to any length you like, the design file is included.

mostly the arm part or the biggest peace
