3D model description

This two part model of a mechanical Tyrannosaurus rex features articulated legs and arms. Mech Rex has an upper and lower jaw that move together when his mouth is opened or closed. His upper jaw (head) prints separately and snaps in to place.

No support is needed for this mode. It can print at 75% scale if you desire a smaller model. I have printed this as small as 50% scale however his arms will not move at this size.

Update: Some people have had trouble with the arms coming loose and falling off. I have uploaded a V2 version with a fix for the arms. I work hard to make sure my models do not have issues but in the case that I miss something I greatly appreciate your feedback. Thank you! And happy printing!
