This model comes with multiple files, with the entire mask as one, or with the spikes separate for printing ease.The model also is separated into two sections models, with cuts, and without cuts in case, you prefer a clean look or to make the cuts in the mask yourself.If you have any issues with the model, I am happy to help or if you see any issues with the model, I can fix it asap for you.There are also files with extra tolerance for the spikes to slot in easily.
