USB Relay enclosure

prusaprinters

This is a case designed for 1 channel USB relays, the kind you can use to control electrical appliances with your computer, or hook them up to a MQTT server to provide IoT/smart home devices to your digital assistant (Alexa/Google Home) or other house automation.There are versions with and without wall mounting holes. You'll need M3 screws to secure the board to the case and to secure the lid. The threads are modeled into the file, but may be a good idea to use a tap to better form them, especially if your printing is not very precise, like this PETG version I made.
