Customizable Flex Joint Mold

Printable mold for flex joints of customizable size, including those for Gyrobot's [Flexy-Hand](http://www.thingiverse.com/thing:242639). We are currently experimenting with Smooth-On's "Dragon Skin" silicone but other materials may also be viable. Up-to-date material information for these joints can be found at https://github.com/daprice/Flexy-Joint/wiki/Materials (If you're testing any other materials, your contributions are welcome!)

Unlike Gyrobot's Hinge Mould, this is one piece to minimize cleanup after casting, and the open ends can be sealed with tape. The silicone we've tested doesn't stick too much to PLA so the finished pieces can be pushed and/or pulled out easily.
##Updates
* Update 6/24/14: Each size in the mold is labeled. You can also provide a text label for the whole mold.
