737 Annunicator-Simple

This is the simplest 737 annunciator box to 3 print. You need lots of these for a 737 build.
The body is sprayed black after printing in white. This allows for great internal reflection of the LED's. Dont forget to spray the edges of the lens covers black too.

The Lens was created from 1mm clear perspex and cnc cut.

I use two 5mm clear ultra brite LED's. These come in various colours.
I have also included the light stop cap, this prevents light bled from the annunciator itself and prevents backlighting illuminating the caption through the LED bodies.
