SpoolSense Reader for Cereal DryBox in "AMS Style" - LCD 16x2 and RGB status LED

Im made a case in AMS style for NFC/RFID scanner SpoolSense.org for managing my spools and DryBoxes with Spoolman. The positioning system of the NFC antenna is flexible to adjust the distance to reach the NFC tag. The RGB LED shofs different stati and the color of the filament.

This enclosure is part of the SpoolSense ecosystem – an open-source project for tracking filament spools using NFC and works as endpoint for Spoolman.
