I took @Stamos's lid idea and added a post to use for LED fiber optic style illumination (I'm still tinkering to get the filament holes lined up better - it works as is, but it could be better).
The lid is for the @Stamos's case that was edited by @depeche for the Libre Computer.
Simply use 1.75mm filament (I used Crystal clear), slide it down the holes, trim to desired length, and you've got indicators on the lid now.
I also let them be a little long, so I could push them down until they touched the board and stick up about .5mm above the top so they look nice and bright (make sure to trim the ends as square as possible to allow the best amount of light to flow up the filament).
I also edited the original case to allow for the LED post (it works without the edit, but it seems to fit more gently with the case mod).
The author remixed this model.
