Parametric filament ruler (** Use the Updated Version)
thingiverse
A remix of the ruler from https://www.thingiverse.com/thing:3886663 **A better V2 at https://www.thingiverse.com/thing:5998096** I accumulated loads of different filament brands and roll sizes with no real way of knowing how much was left on each roll. I took the design by hsiehty and remixed it to * Label the notches rather than have square and circular holes * have as many, within reason, reporting notches as you want * allow you to specify reporting at a %age or m left (label is always in m) * allow you to add an unlabelled 10m notch Use the Customizer to make one for yourself if you don't have Openscad
