A mask of Sans from Undertale. Mask can be printed with any settings as long as you have supports. Mask already has slots for running strings through. It is a bit heavy and will take a while to print. Took 24 hrs on my Taz 5 with a 3.2 layer height. Model created in Maya and then cut down in Tinkercad.

Don't have a printer this big? Check out Komb's remix of this model that was sliced and added a hole in the nose here. http://www.thingiverse.com/thing:1856480
