This is a retainer for goggles or a headlamp on a helmet. I designed it to retain goggles on a ski helmet but it would well work in other applications.

I printed with PLA after my latest ski trip when my goggles would annoyingly flip over my helmet after removing it from my head.  Can't attest to durability yet so you may want to print in PTEG or ABS. For Bed Adhesion, I'm finding it's best to use brims or you may end up with a mess. Fasten with double stick tape lower than you think is needed. I recommend having someone help you position them with the helmet on and goggles lowered.

Colors and size can be changed in Bambu Studio.
