Description

After printing some prototypes of the Montana Mask, I noticed a few geometry issues in the original model that could cause defects in the final print. After a week of tweaking, I ended up rebuilding about 85% of the design from scratch in Fusion. Key changes; Modifications in model symmetry to fix defects. Example: Seam under the chin. Adjustments to nose and chin shape for improved comfort and fit. Reworked strap loops for added strength when using different materials, and to facilitate printing without needing supports. Added simple grille to help protect filter from physical damage, and prevent wearers from putting the filter in backwards (I've pictures of people doing this unfortunately). The only thing I haven't modified was the original Montana filter flange which I've included.
