Introduction: 3D-Printable Respirator
This is a fully 3d-printable respirator design requiring minimal materials to make. Check out the thingiverse page for it: https://www.thingiverse.com/thing:4258947
Note: this design is not tested, use at your own risk.
To build it, you will need a 3d printer(kinda obvious), at least 15m of filament, TPU(or any other flexible filament) and PLA. Also, it requires wool/cotton/makup pad for the filter(or a real filter if you have some).
Step 1: 3D Print the Parts
For the first step, print the parts. Use your flexible filament for Mask1.stl and PLA for Mask2.stl. You may need to scale the parts in order to fit your face. If you do not have flexible filament for Mask1.stl, you could tweak the settings in your slicer to vase mode, so that only 1 perimeter is made, thus making it more flexible.
Step 2: Assemble the Filter
Take your filter material and fit it in Mask2.stl. Make sure it is not too tight, nor too loose. If it is too tight, you could have difficulty breathing. If it is too loose, it could be ineffective.
Step 3: Make It Comfortable
Take your wool or cotton and glue it around Mask1.stl to make a good seal. It also makes the edges more comfortable on the face. Also, tie an elastic band into the two holes.
Step 4: Assemble the Parts
Take the two parts and screw them in. Make sure to glue it in order to make a good seal between them.
You are done! Make sure the glue has dried before putting it on your face(it got stuck on mine... XD)!

Question 2 years ago on Step 4
If you glue mask1 into mask2, can you still replace the filter in mask1?

Thanks for the reply!
If you glue the two parts together, then you will not be able to replace the filter. Here is the solution though! You can cut a piece of wool fabric that is the same size as mask2, to make a seal that does not rely on glue. Here is what I am trying to say:
Have a good day!
