Simple Graham escapement

My first escapement!
Everything is 3D printed except the pendulum, the thread, the nails and the weight. Anything (ok, not anything, but many things) can be used as weights and as pendulums. It's easy to change and experiment with different lenghts of pendulums and different weights.

If you are having problem with printing the threads on the pendulum attachment, you can try this, which are a bit easier to print: http://www.thingiverse.com/thing:1143549
