I have a lot of hair and almost nothing is strong enough hold it up reliably. So today we begin a quest to 3D print something that can do the job! We'll start with takigama's Hairtie and Chopstick Hair Clip on Thingiverse just to get a sense of what is possible, and modify from there on future days.

Settings: MakerWare "standard", without rotating the objects at all. These are very well-designed to print without supports.
