[Only 1g filament, 15 minutes] Wide label slot (for leftover filament disposal/storage)

A 14mm*50mm wide label slot that can hold labels within this size.

I've seen quite a few storage boxes and containers on this site, but those with label slots aren't suitable for me, and those that suit me don't have label slots. Considering the size, weight-bearing capacity, aesthetics, and material saving factors is a real headache, thank you to all friends who make storage boxes for giving a picky person like me options. I made my own label slot so I don't have to worry about forgetting what's inside the drawer after it's closed. It can be glued to the surface of a box or the spine of a folder. An extended usage is to attach small magnets to both the back of the label slot and the front of the drawer, making positioning, adsorption and replacing label content very convenient.
