Jack of blades mask

I used the low poly mask as a base and used Blender to modify it to what it is currently. Did not change the size much. Have not had a chance to print it yet. Using makerbot software and a replicator or replicator2 to print it is about an 8 and a half hour print (in theory).

This is my first attempt at 3d modeling. Hope ya'll enjoy!
