On-Spool Filament Level Guide

There are a lot of filament level indicators out the but they all seem to require that you have direct access to the spool or sit on the outside where it is difficult to see the filament level. If you are using an AMS or dry box then this can be inconvenient so I have developed this gauge which fits neatly onto a standard BambuLab reusable spool and allows you to see the filament level at a glance without opening the AMS/Dry Box It has graduated lines for each 100g of filament (in my profile Red is for the odd numbers and Black for the even) which make it easy to see at a glance how much filament you have left. This does sit between the RFID tag and the reader in the AMS however I've not yet experienced any issues with the AMS reading the filament type but please do message me if you have any issues
