Original Mask Model File: https://www.thingiverse.com/thing:4237783 After viewing ctwiles' YouTube video, I printed a spare mask. I think hot melt glue may not be the best method for filter replacement. So, I created a simple design using the elasticity of one layer of PLA to hold the filter. 3/31 Update Following several test prints, I realized there was an opportunity for a failed print on the elastic layer. To avoid this, I added some bars to the model and recommend printing with a 0.1mm nozzle setting and base support.
