Right now? No.
Could I have 'em poke out the other way? Prolly. Can I make it smaller? Not really.
see I don't really have room for screws because I have the master valves back there and they'll penetrate.
And frankly the thing is too big to print flat because my bed isn't that big. Print it at a 45 degree angle so the labels don't look like ass? Well you just gained 41% more length lol.
And this is why I design, then think about it, then go "that's not going to work" and reconsider. Somewhere I have my wire carriers as gothic arches... those didn't print worth a shit. Prolly took 4 iterations to end up with what I did. The ECM schema is on Version 3.
