Housing for 1 channel 5V relay to be installed inline on power cord.

thingiverse

This box is specifically designed for 50mm x 26mm 1 channel optocoupler relays, ensuring a secure fit that prevents the board from moving inside the box during use. To keep things organized, guide pins are strategically placed to prevent the board from shifting around, and slots have been carefully cut into each end, allowing for easy installation on a 120/240 power cord. This setup enables users to control the relay's operation using only three wires, which connect to a Raspberry PI with a female connector on one end and a male connector on the other. Inside the box, there is ample space for cables, leaving room for any additional components that might be needed in the future. With the possibility of adding holes or strain relief in an upcoming update, users can rest assured that their setup will remain stable and secure. The lid of the box has been designed to accommodate taller relay boards, providing extra cushioning between the board and the relay. This feature is particularly useful when working with wires that need trimming or when a soft buffer is required for optimal performance. This housing is built specifically for optocoupler relays like the GEREE 1 Channel Optocoupler Level Module, which can be found on Amazon at https://www.amazon.com/GEREE-Channel-Optocoupler-Level-Module/dp/B00TGTX23I. The ultimate goal of this setup is to integrate it with Octopi PSU plugin, allowing users to remotely switch power to their CR-10S printer from anywhere in the world.
