In Use Signs - Various

(See my "On Air" sign for an example of one lit up)

This sign is intended to be lit up to warn others that a room is "In Use" or occupied. Such as for outside a darkroom door.

We haven't figured out the electronics yet. Planning to use something like a WS2812b LED with a wifi microcontroller. "Hey Cortana, I'm recording now!" (or something like that).

Temporarily, we stuck a couple christmas tree lights inside, connected to a wall switch inside the room.

There are 2 and 3 sided wall-mountable versions and a 2 sided desk mount version. Each has variants with and without integral letters, so you can either print letters in another color or paint them. The 3 sided version also comes in a 2-part one with a removable top to avoid the support marks showing through the translucent filament.

Included is a wall mount intended for the wall signs to hang from.
