About this 3D model

Z-REX's (pronounced "Zee - Rex") are small, easy and fun prints of a dinosaur model... with an opening mouth / jaws and teeth that bite. No support required... just print it with at least 3 shells and 50% or more infill to make the jaws / mouth springy so they open and close. At standard scale Z-REX's are 125mm long. You can safely uniformly scale them up (as this will increase internal clearances), but scaling them down may result in the mouth / jaws not moving. Please refer to the images provided and print instructions for additional information... and post photos of your Z-REX's. Z-REX's work in the same way as my SHARKZ / CROCZ / EAGLEZ etc. These prints can be found at: 'Snails' https://www.myminifactory.com/object/30353'Fish Fossilz' https://www.myminifactory.com/object/30368'Bugz' https://www.myminifactory.com/object/30415'Sharkz' https://www.myminifactory.com/object/30262'Snakez' https://www.myminifactory.com/object/30413'Ratz' https://www.myminifactory.com/object/30361'Crocz' https://www.myminifactory.com/object/30274'Woodpeckerz' https://www.myminifactory.com/object/30348'Eaglez' https://www.myminifactory.com/object/30290'Catz' https://www.myminifactory.com/object/30296'Scorpionz' https://www.myminifactory.com/object/30301'Piranhaz' https://www.myminifactory.com/object/30424 Note: If you like this check out the rest of my fun and practical designs.
