Raspberry Pi LED Extension

I drilled 3 holes in the top of the case and glued transparent PLA filament pieces in these holes. Now I can see if the raspberry has power, if a networkable is attached and the flickering if there are TX/RX activities.
If you want to do it perfect you have to grind the PLA wire a little bit smaller and put 4 pieces in. Achim
