Prusament Filament Indicator PLA PETG meters grams

A filament indicator for Prusament   classic spools (non NFC) .

Designed in Autodesk Fusion, source file included. All text and most dimensions are parametric. I am open to suggestions for improvements. This is my version for Prusament NFC Spools :
