Portal Silhouette Art
Very easy to print, no supports needed, the back slots into place securely.
Print more than one back so that you can change the mood by changing the background.
I have a wide range of silhouettes which you can see here: https://www.prusaprinters.org/social/94081-3dprintbunny/collections/34911
