Sonoff Dual R2 and POW R2 enclosure

thingiverse

This is a custom enclosure I designed to enhance the safety of my Sonoff Dual R2. The device will be used to control power to my 3D printer, and the second outlet is reserved for future use with a low-power heater in a dry box. The cable glands provide strain relief for cables as well as protecting against prying fingers. Additionally, the case is secured together to further boost safety features. There are flanges on either side of the enclosure that allow it to be screwed down securely using 4-gauge 8mm wood screws. I have attached mine directly to the underside of an Ikea Lack table. ---==== Update - December 12th, 2019 ====--- This enclosure is also compatible with the Sonoff POW R2 device. ---==== Don't forget to join the earth wires! ====--- I would like to thank SuperHouse for inspiring this project (https://www.superhouse.tv/21-six-sonoff-secrets/).
