Bat Signal Night Light Cover

UPDATE 3-20-18
The original base model didn't print the inner ring. I updated the design to fix that issue. I also uploaded models for 1,2, and 3mm thick acrylic sheets. I also uploaded one where you don't need acrylic to attach the Batman symbol.

This is a replacement cover to night light pictured (I got it for $2 US). The current idea to glue a piece of acrylic just inside the front of the base piece. Then the Batman symbol to the acrylic. I also want to glue the back piece on to the base.
