HC-SR501 Pir Wall Support 3D print model

Hi!

I´ve made a arduino pir (HC-SR501) wall support for an alarm project that i´ve been making for the past 2/3 months. The support includes an wall mount, an arm to extend the support, a box which is the front panel where the PIR will be secured to and a back plate to secure this box to the arm. In this project, i´ve added 2 holes to hold the back plate to the box but there is no need to use them because the back plate fits perfectly in the box. Im going to upload the rest of the parts of the project and a tutorial video of the project for you guys to make it if you want to.
