Filament Sample Hanger

I needed a better way to display the Samples for my 3d Printing Setup. I built the box to take advantage of my steel 3d Printing Locker. This a loose remix as I wanted to be able to hang and label my samples. One change I would make is tuning the bottom of the slots to create a wedge to hold the samples in place. It hasn't been a problem for my setup but I could see it being a problem in the future.This model will also double as a desktop sample holder since the samples are tilted so they are visible.The Calibration disk for multi color filaments can be found here:https://makerworld.com/en/models/492410-multi-color-filament-configuration-disk-mcfcd
