About this model

* Oye! Oye!** Brenda the articulated battle tardigrade has been released into the wilds of 3D printing! Join the Horde to be among the first humanoids to learn about the next epic project from Zheng Labs! We now return you to your regular model description. * Here's a basic torsion catapult. It uses one or more elastic bands to launch a U.S. penny if you print it at 1:1 scale. You probably won't get enough torque to be impressive with fewer than 3 bands. Penny not included! *
