With this addon you can nicely integrate a PIR motion sensor to your DS-102 light switch or every other customizable smart light switch.

The case is specifically created for the Grove Adjustable PIR Motion Sensor but with frensel lens of the Grove PIR Mini to be less noticeable.

I have added the Autodesk Inventor files, if you want to modify the hole for the fresnel lens or everything else.

Pay attation the the bottom layer infill pattern for the "DS-102_PIR_Top". I used Archimedean chords as you can see in the G-Code.
