Keychain Lithopane - Customizable

Make your own keychain! Use any image - selfie, loved one, fav band.
Upload any image and make your one-of-a-kind key chain.
To help you print in different colors I improved my plastic opacity test print. See instructions for more details.
I included an improved version of my opacity test STL file so you can find the best number for the layers setting based on the color of plastic you will be using.
NOTE- I have some detailed image prep notes in my instructable here:
