PIR Motion sensor case

thingiverse

This case is a 2 part matching box. The idea is to mill it with the CNC using 10mm material. You can also use a 3d printer if you wish. There are few parameters you can modify. I have cnc'd this one and adapted few of the measurements. Now, updated to increase internal height, so there is enough space for those electrolytic caps. Instructions These sensors (SR501) could be found under $2 in ebay.
