Safety razor blade disposal case

Print as two separate parts. The lid can be printed upside down so you don't need supports.  then glue them together (I used CA glue). There are keystones and registers to help with alignment when gluing. They will not hold the lid on safely on their own.

You can probably print this at 0.2, but the keystone and registers that are very small. You can cut them off and still glue them together.
