This is a 1:1 scale physical mockup model of the SONOFF BasicR2, also fully compatible with the newer SONOFF BasicR4.

The model accurately replicates the outer dimensions of the device and is intended to help you check installation space, test mounting positions, or design custom accessories and enclosures. It includes all major contour lines and port positions, allowing for reliable size validation before purchasing or finalizing a design.

Whether you're planning to embed it in a case, mount it in a box, or incorporate it into a wall panel, this printable model gives you a hands-on way to test fitment in advance.
