Security Sentry

thingiverse

This three-part mount securely holds a Pi Zero W, an Arduino Nano screw terminal breakout board, a motion sensor, and a Pi camera in place. Its primary purpose is to be mounted in a garage where it can capture time-lapse video of ongoing projects. The Arduino Nano screw terminal breakout board serves as a user-friendly interface between the Pi Zero and other components, enabling solderless connections. To connect door sensors with CAT5 wires, I plan to utilize the row of holes near the RPi, securing them in place with zip ties. My first print of part number one was successful, but subsequent prints of parts two and three were hindered by unrelated printer issues. After resolving these problems, I modified part two, only to discover that its attachment points were too small for my available screws. To address this issue, I enlarged them and reduced the part's size to minimize print time. Considering an alternative approach, one option could be to enclose the entire setup within a single unit, but this will require further exploration by the reader. The third part, which houses the camera electronics, is slightly cramped but printed without any issues. To assemble everything securely, I have ordered small screws that can replace my current wood screws, which are too large for this project. I am weighing the benefits of snap-together construction against the need for a complete reprint of all parts.
