Beautiful buckets with lids problem

Positive in this bucket is: he has a comfortable height an appealing, not to bulky design. Not so good, I like that the swing lid unit is working incorrectly. The first copy went back because the distances of the swing lid insert for residual cover were very different. Looked unsightly.

The second copy of the cover is worked in total something uniform, but he is now proposing when you swing back slightly. It would have also liked it better when the Swing application slightly milky (like on product picture) and would not be transparent.

It should be possible to build this Swing application so that the clearance on all sides is equal.
