Long Face Mask Ear Saver

This is a derivative of Another Face Mask Ear Saver by yamanub, but I ended up changing everything.  

My face mask is hand made but the elastic was too short for my fat head. I also needed bigger hooks for the 1cm elastic. 

The total length is 25cm which fits diagonally on my Ender 3. The outer hooks give you 22cm (8-5/8") of extension, one inner and one outer hook for 20cm (7-7/8"), inner hooks alone for 18cm (7").

In Cura change "Top/Bottom Line Directions" to "[0,90]" when arranging the model diagonally on the print bed, otherwise the default line direction ends up perpendicular to the strap and is a point of weakness.
