Fish Fossilz are an amazing one piece print that wriggles, twists and bends in all directions. It's an easy print that only uses about 13gm of filament (with recommended settings).
Do not use support as that could stop the joints printing separately / free. Raft is recommended as it helps with removal from the build plate and ensures you can break away the bones without damage.
As soon as the Raft is removed 'Fish Fossilz' should be super flexi.... bend twist and wriggle. Another great fun example of what is possible with 3D printing.
Please refer to the images and instructions for additional information... and post images of your Fish Fossilz finds!
