Montana Mask Button-hole elastic add-on

thingiverse

The Montana Mask at https://www.makethemasks.com #makethemasks for Covid-19 safety is really great. Tying elastic straps through the holes to fit it snugly was a challenge, so I came up with this button-hole elastic adapter for the mask. Using button hole elastic and this adapter makes the mask's tightness adjustable and easy to put on.\r\n\r\nJust print four of these per mask (see scaling, depending on mask size). Insert them into the holes on the masks with a dab from a hot glue gun, or a couple of drops of superglue.
