My first adventure in manually changing filament during a print (but it can be printed in a single color), this Allah Calligraphy keychain was made with the calligraphy being a bit taller than the base shape to make it so that you can simply change color at a specific height. I used the Halbert bottom and top surface finish to give it that Islamic geometric look.

I made this for a friend, please feel free to download, modify, and share alike.
