simple hanger for filament swatch

I wanted to add swatches/samples to each of my filament bins (4L cereal bins) - so I created this quick hanger in tinkercad.

They're just two layers thick and printed on end, you can batch up a lot of them and print them quickly.  

I used hot glue to attach them, using a swatch and hanger together to align/center the hanger.   

They're designed to be used with Whity's Filament Swatch 01 https://www.printables.com/model/607513-filament-swatch-01
