After several remixes from other colleagues, I have modified this sampler of mini filament spools so that 30 spools fit inside. I list other improvements:

- The base is printed in a single piece, saving time and filament.
- Added a slot to insert a small paper with the types of filament that are included inside.

Plate 1: Mini filament sample. Print with the parameters best suited for the type of filament you are using.
Plate 2: Spools in 2 pieces, they are assembled together. One side includes an area to attach a 10x16mm label with filament model data. NOTE: All spools designs can be https://makerworld.com/es/models/56653#profileId-58286 but only a few have been adapted for the label and this filament version.
Plate 3: Base of the sampler.
Plate 4: Cover of the sampler.
Plate 5: Duplicate hooks for the correct closure of the sample book.
Plate 6: Protector of the written text.
Plate 7: Modular single shelf, will also fit above or below others.
Plate 8: Shelf to insert 4 samplers box. It is designed to be installed on a vertical surface using 2-4 screws.
Plate 9: Handle to screw on the top of the shelf in case you want to transport it.

The original design requires 6 M3 30mm screws for hinge and latch, but I use cut nails.

You can change the spool design from all the different designs that I have collected and designed!
