Filament Sample Card Holders

Update: See this model for the full Filament Swatch System with an updated card holder, full instructions and other components of the system. These card holders are designed to fit the cards from the Filament Swatch System (https://makerworld.com/en/models/544229) I have attached them to my AMS and use them to show which filaments are in which AMS slot. When I put the filaments back in my Sterilite storage boxes (see https://makerworld.com/en/models/478305) I put the cards back in the holder attached to those (I will upload that soon).QR Codes and filament data from https://3dfilamentprofiles.com/
