Hi @yehochanan ,
Working now, thank you!
So, your Faces aren’t completely flat:

Select the top Faces and S, Z, Z, 0 (Scale them on the Object’s Local Z-Axis to 0). Then force them to be Flat Shaded with CTRL+F > Shade Flat:

Now there is the weird Shading on the D-Pad. That’s because of inconsistent Normals:

Select everything with A and then SHIFT+N. That should fix it.
Did I forget anything?
