Enclocure for BATE Silabs CP2012 serial USB adapter with transparent filament pieces as fiberoptic light-guide for LEDs

This is a small remix of my previous design https://www.thingiverse.com/thing:2848912 of the protective enclosure for CP2102 USB-serial converter from Chinese manufacturer BATE ( in example item #292016436732 on eBay)

The only new thing are round holes with thickened walls to hold a piece of the transparent 1.75mm filament which when touching the surface of LEDs act like fiberoptic light-guide. https://youtu.be/nv7oq3RlJS4
