/diy/ - Do It Yourself

Any clue what the problem here might be? The print consists of a tall and pretty thin frame section in the background, this prints perfectly (two walls thick, which is why the infill is visible through the side), and a tree support in the foreground. The actual part itself prints perfectly, and so does 90% of the support, but this one side of the support has these huge holes. I don't think it's extrusion multiplier, because the part prints perfectly, and I don't think it's the speed I'm printing at since the entire support prints at the same speed and only this one face has any issues. The opposite side has no issues. You can even see that the issue happens even on the skirt at the first layer, the edge there looks a little frayed even though it's perfect everywhere else.
