Tyrannosaurus rex diorama 3D print model

This is my version of the king of dinosaurs, Tyrannosaurus Rex, it is a diorama with a base, it is for 3D printing its size is 38 x 11.5 x 9.6 cm without base, basically 1/40 scale. It has 13 pieces, there are 2 types of head open mouth and closed mouth (both types are included) and the head has space to place neodymium magnet 8 x 8 x 4 mm, the body parts have to be glued to stay always together except for the head that can be changed and stayed together through the magnet.
