Diving mask Adapter for medical filter

myminifactory

This adapter takes 2 or 3 fiters. For long time use at once, 3 filters makes it easier to breath.  If use only 2 filter, must cover the 3rd with provided cap model.  The filter inner diameter 22.5mm Mask model: M2068G   In my print, I use ABS, but any material will do. If the printed part seems too tight, rescale 1 or 2%. It will depend of your settings.  After print, some cleaning might be necessary for a best and smooth fit.
