Customizable Mask Strap

Customizable strap for surgical and cloth masks.
(Also available at grabcad - https://grabcad.com/library/customizable-mask-strap-1)

The design was inspired by the model from the following link:

I decided to leave some blank space in the middle of the object for customization.
Users can easily edit the STL file in Tinkercad (as illustrated) to write a name or sketch some symbols, …etc.
I’ve been printing this part with PLA and it behaves very well. After a while, it conforms to the shape of the neck.
