Ski/Snowboard helmet mask holder
A 3d printable clip that goes on your helmet strap and allows you to wear an ear-loop mask over your helmet.
This makes it easier to take on/off without having to take your helmet on/off. Also a bit more comfortable vs having earloops inside.
Best printed with PETG with the "slot" facing vertically.
PLA will likely be too brittle.
Supports should not be necassary if properly configured.
