A model of the 'Loki Mask' from the Movie 'The Mask' starring Jim Carrey. The model is a single mesh and therefore optimized for 3D printing. Its 22cm in height, can be scaled up or down of course. Google 'Loki Mask' to get ideas for casting/painting ideas. Hang it on your wall and it will look great.
Edit 1: Uploaded the high quality version. But i am leaving the low quality version too, just in case, when your computer/slicer can't handle the high quality version (most of the modern computers should be fine, including entry level PCs), you could try the another one. Enjoy.
