- Expect a colored and improved design in the feature. *
It opens and closes, and the key is removable in both states. I overdid it a little, as the mechanism to hold the leaver can slide up and down so a complete 360Â° turn is possible, which also "disables" the lock to avoid closing it completely (child proof? :-) )
Not as neat as my last thing http://www.thingiverse.com/thing:17822 but I am glad I figured out something that actually works at this scale!
I love making tiny things I love thingiverse... even withthe new design. keeps on ranting Multi file upload > New design ... Someone please write a Thingiverse client that processes a folder with images and textfile descriptions :-)
Anywayy - - - Again, I did not skip an earring, but as it did not print nice I did not upload yesturday's design. Can you believe it? A simple spoon-knife-fork earring gave me so much trouble, but this one worked right away- so here it is.
THIS one works even though I designed it at 200% scale at first, but left enough tollerances.
Excuse the rough images, I just used a little of tape to hold everything in place. A few drops of glue arround the corners or nail polish (color it with gold, metal effect etc.) should do.
The only thing that needs a change is the U shape lock:
You can only lock it at the moment if you press it down a little as otherwise the lock can not close. I left too little space in order to let it slide further, but it actually adds to the design (as it now makes a "click" noise when the leaver slides over the locking mechanism).
Perhaps I will update it someday, and make a more traditional curved lock-lookalike.
The key is designed to fit only this lock, but at this scale it does not work well (I added a thinner second key that should fit easily).
At larger scale you could print the key and center wheel mirrored (or the whole lock) and then you have two locks that only work with their original keys :-)
For a more complex key/teeth type of lock I would need to print it larger, but it could be done with a more complex inner wheel that just turns with the right key pattern.
If you want to avoid loosing the key, use some string or use as a second earring; Or glue it into place so the key can not fall out :-)
You could use the lock instead of the earring loop, but as the locking mechanism is simple, you risk loosing the earring.

-Print with low or normal support settings, highest quality, laying...
-let it cool so it does not bend when removing from the raft.
-glue the parts together at the corners.
-It is easiest to put the tiny "C" shaped locking mechanism part over the center's leaver so it stays in place when you close it.
-use s knife, tweezers etc. to widen the key hole or scrape plastic the key if it does not fit right... or increase the tollerance gaps / diameters...
added a key with bigger hole to wear as second earring, still testing
