SONOFF MINI-RBS extender for shallow backboxes

⚠️ Safety Notice: Please print using flame-retardant materials (e.g., Bambu PC FR) to avoid long-term electrical hazard All electrical installation must be performed by a qualified electrician This is a wall spacer designed for the SONOFF MINI-RBS module used in motorized roller blind control applications. MINI-RBS enables you to convert traditional up/down roller blind switches into smart controls. However, in many homes, the wall boxes are too shallow to accommodate both the mechanical rocker switch and the MINI-RBS module behind it. This spacer adds approximately 15mm of extra depth, allowing you to install the smart controller without replacing the wall box. To ensure broad compatibility, this model does not include screw holes. Instead, it is designed to be pressed and fixed into place using longer screws that pass through the switch panel, through the spacer, and into the original wall box.
