I am trying to print a hing in one piece. The gaps along the vertical faces are fine, however, the gaps on the top/bottom do not print correctly.

I simplified this model to just two rectangles on top of each other.

In the top/bottom gaps, there is a single solid layer, the infill, the gap, infill, then another layer. There should not be infill in these gaps.

The gap measures .2mm. The problem disappears when the gap is increased to .8mm. I cannot have a gap of more than .3mm because the two layers must partially adhere to print properly.

Thank you to anyone who can help.
