This is a cover that will perfectly fit a Eufy Door Sensor, so it can be left outdoors, it is 100% waterproof, you can leave it in the weather, taking rain.

This is a tight fit, I printed it in my K1 with a 0.40mm nozzle.

• Print with 100% walls or 100% infill, I used. Layer height: 0.2mm or less Wall width: 1.6mm Top width: 2mm

Don't forget to print the lid siding up.
