COVID mask strap tensioner

cults3d

There are allready tons of maks tensioners out there, but none are really customizable, and i had to do one for a child. This one is done with openscad, you will need also https://github.com/nohkumado/nohscadlib if you want to use then yourselves, or i have to find somewhere the time/energy to make a working package... but basically you can change in the customizer the length of the strap its thickness width, the number of chevrons and you can imprint a name on it
