Mask Bracket / Frame / Spacer

Update 10/27/2020:

Added an additional STL for mask bracket "bumpers". My biggest issue with the original design is that the corners of the bracket tend to dig into the face a little. This new component is a retrofit solution that remedies this issue by rounding off the sharp corners. The bumpers should ideally be printed in TPU but will still improve comfort if printed in a rigid filament. They simply slide into place on the corners of the bracket. To ensure they don't fall off, I suggest putting a small dab of superglue on the corners first.

This is a remix of the design by 1sPiRe. It inherits all of the great qualities of the original design (comfortable, quick and easy print) and builds on it with the addition of a new method of attachment and adjustment. My contribution is the design of a sliding clasp system. This clasp inserts into the slot that runs down the centre of the mask spacer. To attach to the mask, first make a small crease in the fabric.
