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
Can be printed with a Brim as well. Will need supports and post production. Recommend to be printed in ABS as ABS is easier to do post cleanup work with.
Sanding and painting can be done to make the mask look better, and add foam to make it a more comfortable fit,but can be worn once the supports are removed.
Fresh off of the printer.
After several hours of sanding.
After painting and sealing the mask.
Added an El wire and painted his face black(The battery pack for the el wire was in his pocket). Here it looks OK, but at night, it looked great!.. sadly, I couldn't get any night pictures of it.
