Hi, when printing the extruder mount, I am assuming you need supports given the detail on the back and there appears to be a slot for running wires (although this maybe could be bridged without supports??). I am hoping to avoid printing the whole model and then finding out I can't get the supports off cleanly, etc. and starting over.

Any suggestions on how this is best printed. I am going to be using ABS so I am expecting some challenges with warping as I don't use this often so suggestions to cut down on the trial and error would be greatly appreciated. One thought I had is to split the mount and the backplate and reassemble them with screws and knurled inserts (M4). This way I can print the backplate front side down and the mount facing upward.

Again, thoughts would be appreciated.
