Marvin numbering

I really liked the idea of the Marvins. The mounts are beautiful too. However, I was afraid that after a large number of filament rolls, it would no longer be possible to assign the roll to Marvin.

First I wanted to create a sign on the shelf where the name of the filament roll is, but that wasn't the right solution either, because the names can sometimes be longer if you specify the brand and filament color.

The Marvins can also fall down, so the names are mixed.

I found the best solution to create an Excel list where each filament roll gets a number and the number is assigned to a Marvin.

In this way you can write the names of the role such as brand, colour, characteristic and the associated Marvin number in your Excel list. The best solution was to print the numbers on the soles of the Marvins' feet. So nothing can happen if the shelves are rearranged or the Marvins are mixed, you always know which number belongs to which filament roll based on the Excel list created. 

Thanks again to Rodrim for the beautiful design.
