I used the SVG found here: https://www.freesvgdownload.com/gru-minions-svg-png-free-cut-files/ to create a simple keychain since I couldn't find one. I recommend printing this using a .2mm nozzle else all detail will be lost at keychain size. I used a color swap to change to black for the lines. Scale to required size.
I do not own the rights to the Gru depiction or the movie so use at your own discretion.
