I am building an RGB trap and need a little help sourcing a close to accurate gauge for the front of the trap. Does anyone know what model I need to be looking for and perhaps where I could find it? Thanks!
What may work best is to locate a gauge that has a close enough looking arrow, and if possible, dismantle it and install a custom display to make it look closer to the cartoon display.

There are no meters readily available that are the right size. If you want a working meter your best option is to cut one down so the electronics fit and then redo the graphics.
