Case for 8 relay module

Remixed to fit my common ebay 8 relay module where the board is 138.2 x 56mm.
Includes the slot to accommodate the 3 pin plug.
Just print only a few layers of the top to test for alignment.

I closed the case using 2.5 x 10mm machine screws. Similar sized self tappers will do.

I'm considering including light pipes for the LEDs when I repair my printer.

Update 27-09-2019 .... 2 parts added.
Light pipes for a better view of the relay actuation LEDs and Housing top 2 to match the pipes.
Print the pipes with clear or natural. I used natural because I don't have any clear. The natural worked quite well but clear would be better. Glue them in then brush black paint on the outside of each light pipe to stop light bleed. Be careful with light pipe orientation.
