This is a WiFi Relay Board Holder for ESP8266 12 volt 4 Relay PCB. Because there is a lack of mounting holes on this PCB I made a holder to securely mount it and isolate the back from whatever it is mounted on. The Clamping Bar can have a thin layer of foam tape on it to help reduce Relay vibration and noise. 2, #4x 1/2", Pan Head Screws hold the low voltage side of the PCB, and 2, #6x 1-1/2" Pan Head Screws hold the Relay Bar. If used with hi-voltage this board needs to go in a UL or CSA approved electrical box. Note the WiFI will NOT work inside a Metal BOX. 12 Volt use, the PCB can be openly mounted to plywood.
iPRINT 3D, HATCHBOX, Tianse, etc. PLA, PVC, PETG
Blue or whatever works
Printed with PLA with an extruder temp of 220ºC, bed temp at 45ºC, and fan at 32% after the bottom layers are printed. FR set low ~60% for bottom layers to keep holes clean, then turned up to 90%.
