This is a simple mini servo coupling which connects a "mini series" RC servo to a 4mm rod.
I was absolutely happy to see that this insane detail is printed with ease on my Ultimaker!
This coupling features a tiny hole for a M2 screw which secures the coupling towards the servo. Another hole is there to fix the rod (where you have to drill a tiny hole into) to the coupling.
See a video of the use case as well as more close-up photos here: https://plus.google.com/116416453568555193309/posts/4a1KFqxNY9A
I tried different slicers which gave quite different results due to different threshold values for small details I guess.
The coupling will be used in a flying object which I will release very soon - ready to print of course! Follow me on Google+ or watch for it on Thingiverse.
