Sonoff 4CH R3 box

Assembled box size (without cable glands and cables): 11.6 x 18.6 x 4 cm(W x L x H). Wall thickness at each side is 3 mm.

Please note that the printed model from the photographs has a slightly different arrangement of the cable gland holes - I modified the design after printing the first box. You can play with arrangement of these holes using provided OpenSCAD file.
