This is a simple tool, designed to be paired with a Filament Density Calculator, to get known and accurate lengths of filament.

Printing

I recommend PETG as you want a little flex, but also resistance to creep (gradual deformation of a material over time). Use a smaller layer height (e.g. 0.15mm) to ensure the filament channel can catch and lock the filament (assumes 1.75mm filament).

For this print, I used Atomic PETG-CF filament. To make the raised text pop I used a white paint pen applicator.
