Filament samples and box to store them. I use "Avery All-Purpose Labels, 1.5 x 2.75 Inches, White, Pack of 76" labels from Amazon. I created a line tool as well for the labels to make sure that my lines are consistent.

The samples are designed to be able to be put on a ring should you not require the entire box. The box uses press fit 10mm D x 1.6mm W magnets.

This design is still a work in progress. Some of the potential modifications being added on later larger tolerances for the filament slots in the box, and larger insert holes in the box to allow larger magnets for a more secure closure.
