Spool samples box for 30 mini filaments

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://www.makeronline.com/en/model/PACK%20Mini%20Decor%20Filament%20Spools/44112.html 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!
