Printrbot Simple Metal Locking Extruder Handle V2

This Locking Extruder Handle is a Refined version of my first Printrbot Simple Metal Locking Extruder Handle http://www.thingiverse.com/thing:651391 which locks in both the open position (to feed in new filament) and the closed position (locked down and ready to print).

ALL THE PARTS OF THE NEW VERSION ARE COMPATIBLE WITH THE ORIGINAL VERSION! SO YOU CAN PRINT AND MIX AND MATCH AS YOU PLEASE!

New Features:

- Lock and Unlock symbols on top
- Fancy "printrbot" label on the front
