This creeper has a hoop on its head to attach to your keychain, the parts fit together snugly with the keychain providing extra security.  A single fillament swap creates the face in a different colour, this will work on any printer that can pause-at-layer - MMU not required!  Bridging and overhangs are minimised for easy printing.

Experiment with different colours! Show me your purple creeper with a yellow face!!  Would you use a 3rd colour for the feet?

Printing directions:

• Print the head on its back with the face pointing upward,
• Use your slicer to pause at layer or change filament at layer to make the face a different colour.  You'll want to print the body separately.
• Use your standard profile, and consider lowering acceleration for sharper corners.

The pieces fit tightly together and may require some force.  If they're too tight shrink or use X-Y contour compensation on the lower part.  The keyring also helps secure the two halves.

This is inspired by the Creeper character from the Minecraft computer game published by Microsoft.  I did not create this character, this is fan art. I'm not selling it or representing the character as my creation.
