Smartphone tripod

Foldable phone tripod, inspired by this tripod.
Has a not-so-stupid locking mechanism, just because ;)
The rubber band is not necessary right after printing, but might be useful after some wearing in.

Additional parts:
1 * M5x60 hex bolt
2 * M5x16 rounded head bolt
4 * M5 washers
2 * M5 self locking nuts
1 * M5 wing nut
1 * rubber band (optional)
1 * smart phone ;)
