Adjustable Straps for Face shield - A4 binding sheet - easy punching

Adjustable Straps for Face shield - A4 binding sheet - easy punching Print two straps per Face shield. Another mix of the FaceShield made a plastic strap due to concerns about fabric elastic bands harboring virus that is hard to kill. Plastic is easier to clean and disinfect. I wanted one for the Face shield design I am using so I designed one in Openscad. This strap uses the existing posts of the Face shield design. The original stl file (AdjustableStraps.stl) is 180mm in length. A request was made to add a shorter version. I made two others (160mm and 170mm) that can be used. I have not printed them to verify that they will work but they should. However, you cannot mix one size with another. The distance between the holes/pegs are slightly different.
