After one of my U6 Mesh access points failed and burned a whole into itself, I designed this cap to prevent water from leaking into the device. I added a picture with the hole.

I looked with a thermal camera where the hot spots of the device are and designed the cap to not block them. The LED ring is still visible from the side.

I got good results printing the cap tilted 45° and using oraganic supports.

The cap is designed to fit tightly onto the access point. If it is too tight scale the print up a bit.
