Human Kindness Pin

I made a pin/coin/keychain to give out to people.
There are 2 versions

Blank:
The back is indented so you can place a sticker of your choosing (35mm and below for the default size), and it won't peel up from use. I've got the sticker I'm using in the image gallery.
QR:
The QR code is to ACLU's page on immigrant rights. I'm sure if you have a .2 nozzle or smaller you can get the QR readable in a smaller scale, but I have not tested it.

The 3mf files are designed for multicolored printers, the current settings are for FlashForge AD5X.
Edit: I've added a plate in the 3mf file that has the coin split into it's layers. Additionally if you import the STL into your slicer, you should be able to split into objects and mess around with the layers.

This is my first project, so please let me know if you run into any issues.
