Legrand extension frames

Extension frame if you need extra space under your switch module. I used it for wireless control unit that did not fit into in-wall junction box.

The model is designed to be print friendly, sturdy and filament saving at the same time. For this reason, use 100% infill! The infill is only where it is really needed, most of the frame is hollow by model! 

Self-extinguishing PETG is adviced for use in elektricity and electronics (Filament PM brand FRJet or simillar).
