Case for Window Sensor (easier to print)

This is a remix of MakerMaik's case for his great window sensor. (https://www.thingiverse.com/thing:5019573)

I have made it easier to print by adding a small dome. Like this you can print without any support. However, I have printed it with 6 upper shells, which even may not be needed. Also the back part is closed now in the middle.

I have also splitted the upper and lower case, if you want to print it separately
