3M P100 respirator filter protector

Last crawled date: 4 years, 2 months ago

This device provides your 3M respirator gas mask filters with a small amount of rain protection and may help prevent you from accidentally touching the filter material which may be contaminated with corona virus or other hazards.
i recommend using super glue or duct tape to hold the two parts together.
make sure that your print doesn't have sharp edges or any part that could damage the filters.
in my experiments, this does not obstruct airflow. it also helps to protect the filters from being touched and maybe some rain.
the goal with this design was that one should be able to wear the respirator in a shower or while being sprayed with sanitizer, without getting the filters wet. HOWEVER, with this design there is still a fair amount of exposed filter materiel, and i haven't tested this use case so you probably shouldn't rely on this design for anything involving real risk.
this is not tested or guaranteed by anyone so please be very careful and use at your own risk.
the STLs named spray 1 2 and 3 are for an untested version which may be more appropriate for very rainy weather or guarding from decontamination spray.
