REMOVE BEFORE FLIGHT

REMOVE BEFORE FLIGHT... it's used on airplanes for example on things like Pitot Covers, in order to remind the pilot to take them off before flight or they won't have an airspeed reading once they are airborne.
It's a nice thing to print with NinjaFlex or similar.

I uploaded 3 files:

1- 1mm thickness
2- 2mm in thickness
(BTW if you flip the file upside down in the printing program you will have a smooth surface on the side where you can read "Remove Before Flight".)

3- Double sided 2
