Mask Frame (Remix)

thingiverse

This mask comes in two sizes: Large and Medium. The Large size fits most people, while the Medium size is designed for smaller faces. It uses two rubber bands to secure it in place and can accommodate a wide variety of filters. I strongly suggest using Merv 13 or higher furnace filters due to their metal wire frame which maintains its shape. To prevent the filter from falling out, apply two small dots of hot glue on top and bottom. The nose bumper should be printed in TPU material. For the rubber bands, cut a seven-inch piece once and tie it around each side through the holes. The Stacks feature works only with a layer height of 0.2 mm. If you're printing at any other layer height, make sure there is a gap of two layers. At a 0.3 mm layer height, for example, you should create a 0.6 mm gap. I have not personally tried this yet, but that's what the instructions suggest. Additionally, when using a 0.2 mm layer height, I recommend setting the outer layer line width to 0.5 mm.
