Surgical Mask Strap Support for Helmets

I was looking for a way to use a surgical mask while donning a full helmet at the same time.
The masks keep falling from my ears as i put the helmet on.

Found a version that uses a support both above and below the head, https://www.thingiverse.com/thing:4329908 they work, but the hook is too large to fit in the helmet.

So i did a small change to this version that uses a different hook and works much better for my purpose.
