2 channel relay
thingiverse
I tried some other boards and they never matched up very well so I just made my own. This is for a 12v 2 channel relay that I bought on amazon. It would probably work for any 2 relay channel. I didn't put holes in it because I just drill and tap mine so I know it will all line up. If you want to drill and tap your own holes in then I would print it at 100% infill. if your just going to super glue the board on it doesn't matter on the infill. Also, I made it this height so it matched some other pieces on my project, you can adjust the z to make it shorter if you don't need it that tall
