Here is my new version of the helmet/mask of the Witch King of Angmar! I up-scaled it to perfectly fit most heads, 125% larger than the previous version. I also added tabs to make assembly much easier. I can vouch for that, the tabs work perfectly! It almost stays together without glue! The pieces are also much smaller, making for an easy print and A1 Mini capability! The helmet looks best in Silver PLA Matte! But you will want to add glue to keep it together. 

I also made it so that an A1 mini could even print it!
