Mounting Ambika MB in White Metal Case

I am almost ready to mount the finished Ambika in the White Metal Case.

With the case as opposed to the Plexiglass Enclosure , is it only necessary to use the 40mm standoffs attached from the MB to the bottom of the case and no 10mm standoffs on the top of the MB ?

no need for the top standoffs.

Thanks Adrian

Hello Adrian, what spacers are required for the LEDs, from the picture in your guide they look as though they are mounted 1mm from the board.

Hi, no need for a spacer for LED.
Light pipe will work no matter how far the LED is.

Thank you Adrian
