Where to buy breakout board for 12v expansion?

Ya, it must be fan1.  I'm not at my printer now to look.  But what if I want it to be neat and pretty?  I'm working on another build (see projects forum) and I am putting the board at the bottom of the printer and I might put a clear cover over the whole thing to show off the wiring and add some more LED to make it look nicer.

I'm still looking for a breakout board/ sidecar board/ expansion board that I can use to expand 12V screw terminals for several connections.

Or make your own if you want small and pretty with these

I was thinking the exact same thing but I would think if you spent more that the 20 seconds I did searching you'd be able to find the small ones already connected the way you need.  The ones Tim posted I have worked with and they are big and clunky.  Great on the firewall of your hot rod but not the perfect solution for what you stated you were looking for.  Either way you'll come up with whatever works for you.

Have Fun!

When I get some time I will do some searching I have my own project that would benefit from the same thing you are looking for.  It may take me a few days before I get around to it though so if you come up with anything let us know.

Something like that might work, although it says that particular one is for wires 20 gauge and larger as it has 6mm holes.  So the standard 22 gauge wires from fans or LEDs might slop out.

I assume you would just buy 2 of these are wire all your + into one and all your - into the other.

I think typical screw terminals are probably better.
