This is my design for a "Piber Optic" Raspberry Pi fiber optic indicator lights. This was mostly designed as a piece to integrate into Raspberry Pi cases so that the indicator lights can be seen from the outside without having to look though a vent or a cooling fan. Fits the 4b model and adds 3mm to the bottom of the pi. Due to the fiber optic cable being clear PETG filament, the max distance you could likely send the light down the filament is about 9 inches.

You will need one "Piber Optic Mount" and one "Piber Optic USB side" to get the basic setup. I have included a very poorly designed V-slot mount designed for an M5 bolt with a T-nut on it, that can hold the ends of the clear PETG outside of the Pi case.
