弗蘭肯斯坦的怪物面罩，用于Covid-19 3孔沖孔

This is a combination of multiple desig I've seen (Links below). I picked my favorite bits and turned it into this, hence the name. Includes: -> Standard 3 Hole Punch fitting -> Closed Top -> Wider forehead rest -> Hooks for optional over-the-head straps for added support -> Buckle straps for holding 1/4" elastic (can be bent inward with hot watehair dryer to avoid using straps) Let me know any additional suggestio!
