4 Module Relay Case / Mount

thingiverse

Four relay case with mounting tabs, a sturdy setup for the board. The board case closes and secures the board firmly in place using four 3m screws. Two additional 3m mounting tabs are included to provide extra support. Beneath the board, pressure is absorbed by a solid foundation. Designed for smooth printing in ABS plastic, this case is built to withstand heavy use. Four LED view holes allow easy access to the LEDs, while dupont connectors and screw down connectors can be reached from multiple sides. Wire access is also provided for screw down connectors. Thanks to Rodrigo Rodriguez on grabcad for sharing a cad file of the 4 relay board. https://grabcad.com/library/4-relay-module-2 My design differs slightly from this CAD file, with screwholes positioned 0.5mm towards the corners in both x and y dimensions. Component locations are also altered. Multiple versions of this board may be in production. My board has been used for a few years; it's possible that a newer model exists. Check your own board before printing to confirm. If I find differences, I'll order a new board and upload an updated design. I'd like to thank aeroms for his inspiring design ideas. He kindly shared design files in his original thing, which I adapted using freecad. Many of the features are similar due to no coincidence. https://www.thingiverse.com/thing:2405891 FreeCad design file is available.
