SmartSwitch Backcover

This is the back coverage of my selfe engineered SmartSwitch for controlling my rollershutters. The PCB of SmartSwitch fits perfectly into the coverage. By operating the module at mains voltage, the active parts and pins should be covered against directly and indirectly touching. As positive side effect of the coverage, all SMT-Components on bottom side are protected against mechanical damages.
I’ve designed the back coverage for the module with FreeCAD and printed it with my Anet A6 3D-Printer
