1 Relay Board Enclosure (for "Low Level Trigger" relay)
thingiverse
This enclosure is specifically designed to house one 5v relay board, which has a low trigger feature. You can find this exact product on Aliexpress for just $0.60. To secure the relay board inside, use hot glue to attach it firmly to the bottom of the enclosure. For a permanent seal, apply additional glue to close the lid and enclose the entire assembly. Printing this enclosure took approximately 40 minutes at a resolution of 0.15mm. Please note that this time estimate is specific to my printer settings. One important note: The information below has no bearing on the enclosure itself, but may be useful for future reference. I've encountered an issue with this relay board when using it with a Raspberry Pi - due to its low-level trigger functionality, it doesn't function as expected. To overcome this problem, I've implemented a workaround that involves setting the GPIOs to IN or OUT instead of HIGH or LOW. This allows the relay to switch correctly. In contrast, when testing this relay board with an ESP8266 ESP-01 module standalone, it works flawlessly. If you're interested in acquiring one of these modules for yourself, I've included a link: https://goo.gl/RyD1Ox
