Remaining filament estimator

Remaining filament estimator indicates the remaining consumables.
I absolutely love the Bambu Lab reusable spools and I also like the indicator on their labels that gives an estimate of the remaining filament.
So I made one that you can snap onto the spool; that way, you can quickly see if you have enough filament to print your next project.
Optimized for Bambu Lab spools, a reading of 6 for example indicates there are 600 grams of filament remaining on the spool.
(The indicator shows estimated remaining filament; 200g, 400g, 600g, 800g, 1000g)

I have studied and reflected on many works published by Maker World while creating my work, including Michael's Filament Spool Meter that has given me great inspiration and reference. I would like to express my gratitude to Michael!https://makerworld.com/en/models/492449#profileId-406081
