SainSmart 4 Signal Relay Box / Lid
thingiverse
Built a custom enclosure for the SainSmart 4 signal relay and Huzzah 8266 board using Fusion 360. The design should be refined in OpenSCAD for better customization options. Adding ventilation and WiFi signal passage enhancements is a future goal. Installation requires printing the box, aligning input and output sides with the opening, testing for proper fitment, verifying terminal screw access, and applying hot glue to secure relay corners. Wire connections complete the build process. Future plans involve mounting the ESP8266 externally using hot glue, but an internal mounting option is also under consideration with a dedicated 5-volt power cable port. An update will be posted when the design is finalized.
