On Air Sign

This is an On the Air sign.

I created it in three parts. (I'm in the middle of a 5-hour print of something else, so l'll upload photos once I print it this.

The parts are a white shell, a black mask layer with the text and a red layer so that when it's backlit, you can read the message ("ON THE AIR").

I reworked the shell so that it's a bit deeper, and opened up the gap a bit so there would be less post-print sanding of the other two parts.
