This is to slot into weep holes around your house to stop rats and larger insects from getting into the cavities of your home, while still allowing moist air to flow out.
This was modeled after the Weepa Protect Weep Hole Screen
STL are designed to be printed as is
To use, line up the cover with the weep hole, use the pusher to slot into the 6 holes and push the cover into the weep hole. The surrounding skirt is designed to flex to fix your weep hole and cover the gaps
Infill doesn't matter on the cover as it's so thin anyway
You want about 50% infill or more on the pusher
