This is a revision of a strap extension for facemasks with elastic straps that go around the ears (3DPX-013759).  This is a modification of an already approved strap extender (3DPX-013410).  The purpose of this modification is to lower the amount of material used, lighten the hardware, allow more flexibility and add an additional notch on each side for larger faces.  Feedback on existing extentions suggest that the current design may be too small for some, and now puts more stress on the bridge of the nose.  This design aims to alleaviate that issue, while still maintaining the integrity of the design.

The most recent version (V2) has repositioned the upper set of hooks to allow for a tighter print bed spacing.  This will hopefully improve production for those that are printing high volumes.  We've also removed the hooks closest to the center, as we've not seen anyone actually use them.
