This is an alternate case I made for the Xiaomi Mijia Motion Sensor, it takes up less space against a wall compared to the existing case (except for length since I added a CR123 1500mAh battery.
Also with the bigger battery I did the 5 second detection interval modification.
Unmodified with this case you should expect more than 5 years of battery life, with the 5 seconds mod it should be around 2.5 to 3 years.
See here for how to do the mod:

The case is for people experienced with 3D printers, soldering and electronics.
In total producing this case took over 50 draft prints and more than 100 hours of work.

Note the bottom of the case showing marks is because this is of a draft version using the wrong type of support. Final version (in the above photos looks much better)
