Filament sample keychain

I tried using other filament sample prints for my middle school classroom.  The flimsy cards were often broken, lost, or just took too much filament to print!  I also needed a place to put a label on each color so students could request a color for their print.  

This small keytag is only 50 by 25 mm, shows how the color looks at 1mm, 2mm, and 3mm thickness AND is easily contained on a keyring!  No more lost color samples, no more broken samples (the main keytag is 4mm thick). AND I can use a standard label maker to label each sample for easy identification.  No more writing on the sample with a permanent pen!
