Mask Cap Parts

I designed a mask cap for fabric or disposable masks.
You can attach various kinds of filters to the middle of them.

How to design the threads:

1. Make threads for bodies each.
2. Inspect with Sections analysis.
3. Turn the bodies to be arrayed.
4. Make spaces to be fitted with Push and Pull.
5. Fillet the edges on the top.

Wish a Happy Printing!
