Universal filament clip with level marking

thingiverse

This is a versatile filament clip suitable for use with 1.75 mm; 2.85 mm and 3 mm Filament. With its built-in level indicator, users can easily determine the amount of material remaining on the roll, making it simpler to gauge how much filament has been used. To get an accurate reading, it is best to track the amount used after each print (in grams), allowing you to calculate how much filament is still available at the end. The scale can be printed directly onto paper and is located in the Images folder. For smaller projects, the level indicator may not work as effectively due to its small size. However, it can still prove useful in certain situations.
